Justin Timberlake Tells Jessica Biel to Slow Down

Justin Timberlake has told girlfriend Jessica Biel to slow down.

The SexyBack singer, 27, is said to be encouraging the 'Elizabethtown' actress to ease off her diet and fitness regime because he's concerned she's burning herself out.

A source says, "Jessica is under a lot of pressure to stay in shape because there is so much competition amongst young actresses in Hollywood.

"Jessica loves to work out and so does Justin, but lately it seems like that's all she does.

"She's got an amazing body and Justin is trying to get through to her that she can afford to take some time out once in a while and have a burger, some beers and a day doing nothing."

Timberlake's nan recently revealed that she wanted Justin and Jessica to marry in his mom's backyard.

She said, "I just want them to be happy. Justin should get married in Lynn's back yard in Tennessee.

"She has a big yard with beautiful flowers.

"I think it would be perfect.

"Jessica’s really sweet. She's his age and isn't possessive. I think their personalities are a lot alike."
