Jessica Biel Spotted With Growing Baby Bump

On Tuesday, OK! Magazine mentioned that the pop star has been taking on a new lifestyle ever since he and his wife, Jessica Biel, found out they were going to be first-time parents. Apparently, Timberlake is doing everything he can to make sure his wife is comfortable.

"The transformation has been quite incredible," a source told the publication. "Not only does he pamper Jessica 24/7, he also has been reading up on fatherhood the whole time and has totally transformed his lifestyle."

Are Justin Timberlake & Jessica Biel Planning To Move?

It was also mentioned that the singer is no longer a party man; he is reportedly spending any spare time he has indoors to make sure that he's there for his family.

"He rarely goes out," the source said. "When he does he's back by 10pm with to-go food for Jessica."

The site also gave some specific details on how Timberlake makes his wife feel comfortable with kind gestures here and there.

"He's completely in awe of her and brings her home a little gift every single day, whether it be a box of chocolates or a new pregnancy pillow," an insider told the magazine last December. "He gives her fantastic foot and shoulder massages too after getting a few lessons from his personal masseuse."

There is no word on the sex of Biel and Timberlake's baby just yet.
