Justin Timberlake Plans to Win Jessica Biel Back with Third Child After DWI Scandal

Justin Timberlake is desperate to get the sexy back with his long-suffering wife, Jessica Biel, by getting her pregnant with their third child, sources tell GLOBE.

“He worries she’s slipping away from him, and it’s been building up since his embarrassing DWI,” says the insider.

Justin’s panic escalated after the former 7th Heaven star, 42, posted a cryptic post on Instagram for his 44th birthday.

Most of it was standard sweet birthday wishes. “Another year to make memories that I keep sacred in my heart. Another year of joy and challenges being a parent with you,” she wrote.

Then came the sentence that struck terror in Justin’s heart. “Another year growing and evolving and sometimes devolving, with you.”

“To say he was a little freaked out [by that part] would be an understatement,” spills a source. “The post struck a nerve, and her ambivalence concerns him. It shows she doesn’t take any of his B.S. anymore. She’s telling the world it’s a flawed marriage!”

“Justin figures another baby will keep her focused” and by his side, says the tattler. “He knows she’s been happiest when pregnant. That’s when she’s glowing and optimistically looking forward. He figures they’ve always wanted a bigger family — the hard part is convincing her to go for it!”

The pair, who wed in 2012, share sons Silas, 9, and Phineas, 4.

Adds a source, “Jessica has always said it would be lovely to have a girl, and that’s what Justin is banking on!”
