HEIDI Klum admits she’s having a tough time trying to lose her baby weight.

The Project Runway host — who welcomed her fourth child, daughter Lou, last month — says she’s finding it hard getting rid of her post-pregnancy pounds.

“I wouldn’t say I’m back in shape yet,” she said. “Everything changes when you get older. It was different when I was 31 with the first one and now being 36 with the fourth one.

“I think that if you wait too long and it sticks there it stays that way forever. I have to be motivated.”

Klum recently insisted she and husband Seal won’t be having any more kids.

“Yeah, we think so. It’s a lot!” she told People magazine. “The noise factor around our table is unbelievable. There’s so much going on … My husband sit and look at each other and say, ‘Soon there will be No. 4 at the table. It will be even noisier!’ “

Heidi Klum insists she’ll be drawing the line at having four kids!

The Project Runway host and her husband Seal welcomed their fourth child, daughter Lou Samuel, on October 9 at 7:46pm.

But the 36-year-old is adamant she won’t extending her brood further — because her house is noisy enough as it is!

“Yeah, we think so. It’s a lot!” Klum told People magazine. “The noise factor around our table is unbelievable. There’s so much going on … My husband sit and look at each other and say, ‘Soon there will be No. 4 at the table. It will be even noisier!’ ”

“I think that it’s a wonderful experience to be pregnant, definitely, but you have to look at what you can do, and four children is a lot!” Klum added. “It’s a big family. We drive a really big VW bus. Now in September, all three children will be going to school. Try to fit three car seats in the back of the car!”

Seal and Heidi already have two sons together — Henry, 3, and Johan, 2.

Seal is also the adoptive father of Leni, whose father is Heidi’s ex, Flavio Briatore.

Meanwhile, experts have weighed in on Klum’s choice of name for her new born.

“Lou represents a combination of two growing trends: nicknames on the birth certificate and boys’ names for girls,” Linda Rosenkrantz, who co-wrote Baby Name Bible told Us Weekly magazine.

“Although Lou has always been used as a short name for Louise and Louella, it has rarely been heard as a full first name for a girl.”

Heidi Klum gave birth to a daughter Friday.

Lou Samuel was born Oct. 9 at 7:46pm in Los Angeles, Klum’s rep confirms.

The Project Runway host’s husband, Seal, released the following statement Monday night:

“It’s difficult to imagine loving another child as much as you love your existing children,” Seal writes. “Anyone who has a family will tell you this. Where will one find that extra love? If you love your existing children with all of your heart, how then can one possibly find more heart with which to love another?”

“On Friday, Oct. 9, 2009, at 7:46 p.m., the answer to this question came in the form of our fourth child and second daughter,” he continues. “Lou Sulola Samuel was born, and from the moment she looked into both of our eyes, it was endless love at first sight. She is beautiful beyond words and we are happy that she chose us to watch her grow over the coming years.”

Klum, 36, recently insisted she won’t have more than four children.

“We’re outnumbered. Four is perfect. Three is a lot. But four? It’s a lot of work,” she told USA Today in August. “We’re hands-on, and we feel like this is what we can handle.”

Klum has also revealed that she struggles with the last month of pregnancy.

“The last month is unbelievable, how rapidly your stomach goes. It’s huge,” she told Page Six magazine. “The thighs, the butt — everything explodes in the end.”

Seal and Heidi already have two sons together — Henry, 3, and Johan, 2.

Seal is also the adoptive father of Leni, whose father is Heidi’s ex, Flavio Briatore.

Oh! Maybe Heidi Klum hasn’t given birth!

Radar claimed earlier today that the Project Runway host — who’s married to singer Seal – gave birth Friday to a baby girl called Lou Samuel.

The site also reported that the baby was born naturally at 1am, within one hour of being induced.

But a source close to Heidi insists the baby has “not been born yet.”

However, Klum and Seal will probably welcome their fourth child, a daughter, later tonight. So stay tuned!

Heidi Klum has banned her children from jumping on her pregnant stomach.

The 36-year-old model — who raises three kids with husband Seal, and is expected to give birth to a girl next month — took action as she was concerned her exuberant kids might damage their new sister.

“I had to stop them jumping on my tummy. They don’t really understand there is actually a real human being in there,” she said.

Heidi is excited about the new arrival, and admits become a mother again has encouraged her to think about her parenting responsibilities.

She is determined all her children will get good educations, and she has high hopes for their future careers.

“You want them to stay in school and you want them to have a vision of what they want to be and give them ideas and encourage them,” she added. “I definitely want to get involved and do that, think about job ideas.

“Nowadays children look at everyone in the magazines and they want to be a basketball star or on a television show, but there are only so many people who can do those things. But you still should aim or dream for these things.”

Heidi also lashed out at parents who blame the fashion industry for causing young girls to develop eating disorders.

“You can’t blame other people. It’s your own choice and if you have children, it is up to the parent to educate your children so they are healthy and they don’t go into a direction of anorexia or obesity,” she said.

Heidi Klum wears tight clothes in the later stages of pregnancy — so she can show off her “beautiful” baby bump.

The Project Runway host — who is due to give birth to her fourth child, a girl, in October — is so proud of her family and her kids she hates wearing “maternity tents” opting for skin-tight fashions instead.

“For me, in the beginning of the pregnancy I prefer to wear something bigger and looser,” said Klum.

“Then later on I like to wear tighter clothes to show off my beautiful baby bump. In the latter stages of my pregnancy I don’t like wearing a big tent.

“I don’t think you are supposed to and there are any rules – but that is what I like to do.”

Heidi Klum says the last month of pregnancy is the worst.

The Project Runway host — who is due to give birth to her fourth child, a girl, in October — says her body has started to “explode”.

“The last month is unbelievable, how rapidly your stomach goes. It’s huge,” the 36-year-old fashionista tells Page Six magazine. “The thighs, the butt — everything explodes in the end.”

“It’s bizarre. Just as it’s a miracle that you can grow a human being in your belly, it’s a miracle that your body goes back to normal again,” she adds. “I don’t think you ever get back to exactly the way you were, but you do get close. And I’m happy with that. Especially when you see your kid for the first time.”

Klum also spoke about her relationship with husband Seal and what makes him “the one.”

“Aside from his sexy stature? He’s a gentle giant,” she says. “We’re very into family values. If you come to our house in L.A., you’ll see that it’s not a big, museum-like house where you can’t touch anything or sit anywhere. It’s a family house, where three children [Leni, Henry, 4; and Johann, 3] are living. We have toys all over the place.”

Heidi Klum insists she wasn’t an overnight success — she had to work hard to get where she is today.

The supermodel and Project Runway host says she didn’t hit the big time overnight.

“After [winning a German modeling contest], I thought, ‘This is my ticket. Things will happen.’ But they didn’t,” Klum tells Page Six Magazine. “I could never book a job. I was walking around New York for three or four years.”

Klum — who is currently pregnant with her fourth child — recently revealed that she refuses to wear maternity clothes  becasue they aren’t trendy enough.

“My stylist tries to find things that are not maternity clothes, so I’ve been wearing a lot from The Row, by Mary-Kate and Ashley Olsen. I love their clothes,” she said. “Marc Jacobs too.

“You just buy things in a size 10 – when you’re doing a show on fashion, you still have to bring it on.”
