JESSICA Biel is worried sick that boyfriend Justin Timberlake will want to get back together with ex-girlfriend Cameron Diaz.

Timberlake and Diaz — who split in 2007 after dating for several years — are set to reunite on the big screen for the upcoming movie Bad Teacher.

And Biel fears the former couple will rekindle their romance while shooting scenes.

Jessica reportedly pals that Diaz is looking “more gorgeous than ever!”

“What if old feelings come back?” she apparently said. “They’ll be working closely for weeks and weeks…and she adored him!”

But the source adds Jessica is “playing it cool and not showing her fear to Justin.”

Showbiz Spy reported earlier this week how Diaz, 37, is keen to get back with the SexyBack singer.

“Cameron never really got over Justin,” a source revealed. “She’d love it if they got back together and gave their romance another go.

“She’ll be using all her womanly charms to try and remind Justin why he fell in love with her all those years ago.

“Cameron says she’d stop at nothing to try and make Justin dump Jessica.”
