CHRISTINA Aguilera refuses to use Botox.

The singer, 28, says she has noticed the effects of aging since giving birth to her son Max, one, and having a severe lack of sleep.

“I take care of my face by doing the usual routine of cleansing and moisturizing,” says Christina.

“I started using some under-eye cream, which is wise considering I’m now 28 so I have to start. I stay as hydrated as possible. I try not to do too many treatments.”

The Dirrty hitmaker recently revealed that she comes alive at nighttime.

“When the sun goes down my whole body starts to come alive, although I am a little different now because I do have a child and my hours have been turned upside down for him, but I’m still naturally a night owl,” she said.

“If it were up to me my favorite time to work would be between three to four a.m., which is what it used to be before my baby was born.”

CHRISTINA Aguilera says she comes alive at nighttime.

The blonde bombshell feels she only operates at 100% after dark.

“When the sun goes down my whole body starts to come alive, although I am a little different now because I do have a child and my hours have been turned upside down for him, but I’m still naturally a night owl,” said Aguilera, who gave birth to son Max last year.

“If it were up to me my favorite time to work would be between three to four a.m., which is what it used to be before my baby was born.”

Aguilera has previously revealed how motherhood has forced her to change her sleeping habits.

“Now I’m a mother, I am getting up earlier,” she said. “It’s 6am every day but I’m a night owl regardless, which means that, for me, going to bed early means trying to get to sleep by 12.30am.

“My bedtime before I had my child was 3 or 4am, but that’s because I love the night, when everything shuts up and I have a moment to be creative.”

CHRISTINA Aguilera says she loves having red lips.

And the What A Girl Wants hitmaker says she uses “kiss-proof” lipstick so her young son Max doesn’t get covered in his famous mom’s make-up.

“I love having red lips,” says Christina. “There’s just something fun and vibrant about it. I love that extra little ‘pop’ to any look no matter how simple or strong the rest of the face is.

“But I have been using this kiss-proof red lipstick recently so I can kiss Max without getting kiss marks all over him.”

Aguilera, 28, recently revealed that becoming a mom has stopped her from being loud and impatient.

“Being a mom has taught me patience and I think he makes me more peaceful,” she said.

“It’s very important for me to create a really peaceful and safe environment for him because I didn’t really have that growing up.

“So that’s really important for me — to make sure my son feels that.”

CHRISTINA Aguilera says becoming a mom has stopped her from being loud and impatient.

The singer, 28, insists she has calmed right down since the January 2008 birth of son Max Liron Bratman.

“Being a mom has taught me patience and I think he makes me more peaceful,” she said.

“It’s very important for me to create a really peaceful and safe environment for him because I didn’t really have that growing up.

“So that’s really important for me — to make sure my son feels that.”

Aguilera recently revealed that she misses her husband Jordan Bratman so much while she is away from him that she wears his aftershave to make herself feel better.

“I love to dabble in my husband’s cologne. I love the sense of a good, musky cologne especially before bed. I like to get it in my clothes so I can smell my husband,” she said.

The Dirrty hitmaker — who gave birth to son Max last year — says she used to hit the hay at around 3 or 4am, but now heads for bed around midnight.

Aguilera — who is married to entrepreneur and music marketer Jordan Bratman — recently revealed that she finds women sexier than men.

“I think women are such sensual beings,” she told the UK’s Cosmopolitan magazine. “And, I mean, I’m attracted to men ultimately — I’m married and I love my husband and I love what we do together, but honestly?

“If I had the choice between viewing a naked man or a naked woman, I’d choose the woman. We’re just naturally sexier and more beautiful to look at.”

Christina Aguilera has asked Dita Von Teese for tips on burlesque dancing.

The Dirrty hitmaker — who plays an erotic dancer opposite Heroes stunner Kristen Bell in the forthcoming movie Burlesque — is so keen to make her character realistic, she has been asking Marilyn Manson’s ex-wife for advice.

“Christina is meticulous in her preparation for anything she does,” explains a source close to the star.

“She is already training hard to be ready for this role and has asked Dita for some coaching on the more technical aspects of burlesque dancing.

“She doesn’t want to have to use a double for anything if she can help it.”

Aguilera recently revealed that she’d rather see a woman naked than a man.

Christina Aguilera thinks women are “sexier” than men.

The singer — who has a 20-month-old son with husband Jordan Bratman – says she’d much rather look at a naked woman.

“I think women are such sensual beings,” the Dirrty hitmaker told the UK’s Cosmopolitan magazine. “And, I mean, I’m attracted to men ultimately — I’m married and I love my husband and I love what we do together, but honestly?

“If I had the choice between viewing a naked man or a naked woman, I’d choose the woman. We’re just naturally sexier and more beautiful to look at.”

“I feel sexiest in the nude,” she added. “I love a bubble bath with my husband and a glass of wine. He has a way of making me feel sexy.

“We’re team-mates. We know what’s on each other’s plates, what needs to be done workwise, what our values are as far as raising our son, and spending time together.”

Christina Aguilera is working on her “best album yet”.

The Candyman singer has collaborated with M.I.A., Flo Rida, Le Tigre and Santigold on Light and Darkness, which is being produced by Tricky Stewart, the mastermind behind Rihanna’s Umbrella and Beyonce Knowles’ Single Ladies.

“It’s just great,” Tricky said of the forthcoming record. “I wouldn’t say that it’s alternative, I wouldn’t say that it’s different. Christina’s always been an artist that moves the bar and that’s what the great ones do.

“They don’t stay in the same place for too long and this album is just another move for her. I really feel it’s one of her best bodies of work that I’ve heard since Stripped.”

The LP will be Christina’s fourth studio album, and her first since 2006.

But although the album is almost finished, it won’t be released until next year because Christina is too busy working on new film Burlesque with Cher.

“She’s gonna do the film first,” said Tricky. “She didn’t want to not be able to promote this record because it’s going to be a big record for her.

“The album is finished. She’s mixing. She hasn’t made a final decision about what the first single is, but I know everyone feels good about their options.”

Christina Aguilera doesn’t want to be in this picture — and she makes it more than a little obvious!

The Genie in a Bottle hitmaker and her disdain-filled facial expressions attended the 1st Annual Variety “Power of Women” luncheon at the Beverly Wilshire Four Seasons Hotel in Beverly Hills.

Aguilera recently revealed how living with an abusive dad gave her the drive to make something out of her life.

“I witnessed a lot of unpleasant things — a lot of pushing and shoving and fighting and quarreling,” said the star, who was the victim of domestic abuse when she was growing up and also regularly witnessed her father Fausto attack her mother Shelly.

“Growing up I did not feel safe. Feeling powerless is the worst feeling in the world. I turned to singing as an outlet. The pain at home is where my love for music came from.”
