Justin Timberlake is reportedly a changed man, and it's all thanks to Jessica Biel's baby bump.

According to a report from OK! Magazine, the singer might be cutting down on appearances and gigs to be able to become a "hands-on" father.

"The transformation has been quite incredible. 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," the source told the magazine.

Now, Justin Timberlake reportedly just goes from work to home as he stopped going to parties and after-show events so he would be back at home by 10 p.m. For good measure, he even brings food to the pregnant Jessica Biel.

In a previous report from the magazine, Jessica Biel's baby bump had Justin Timberlake so happy that he's been showering her with gifts.

The source explained, "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."

"He gives her fantastic foot and shoulder massages too after getting a few lessons from his personal masseuse."

And nobody is ecstatic as Jessica Biel, who's glowing from the baby bump. The source claimed that the actress knew that Justin Timberlake would "rise to the occasion, despite being totally terrified of fatherhood and its responsibilities."

Meanwhile, Inquistr reported that Justin Timberlake and Jessica Biel appeared to be working on a movie together despite the baby bump news.

"The film is called 'The Devil and the Deep Blue Sea,' and it is currently being shot on location in New Orleans, Louisiana," it said.

Justin Timberlake will reportedly lend his music for the film's soundtrack, as well as supervising the score. Meanwhile, pregnant Jessica Biel will be starring as Penny who will die in a fatal car accident.
