Things may be getting a little rocky for Justin Timberlake and Jessica Biel.

There have been updates on their rumored divorce plans.

OK! Magazine has reported that Jessica Biel fears cheating while Justin is on tour so she's insisting on touring with him.

A source reported, "Justin was in shock when Jessica surprised him with the news. Being apart from our spouse for weeks or months at a time isn't healthy in Jessica's eyes. She fears she and Justin will grow apart. . . Jessica is well aware that women throw themselves at Justin when he's on tour."

The source continued, "The temptation is there, and that makes her very uncomfortable."

Earlier this month, Justin Timberlake's grandma weighed in on the famous couple's relationship, partially shutting down divorce rumors.

She reportedly told The Sun, "They do love each other dearly but they are apart so much it's going to be hard going for them. I think Jessica finds that really tough."

Grandma Timberlake continued, "She's on her own a good deal . . . if he's not coming back at night that puts a strain on things, of course it does. It's hard to keep it all going but you have to have faith to keep it all going."

Divorce rumors may just be rumors, though.

Classicalite.com reported that Justin Timberlake and Jessica Biel were recently plagued with cheating rumors after Justin was seen with a mystery blonde woman.

An update reported that the woman was actually the "Mirrors" singer's cousin.

While divorce rumors and updates are made, Justin's tour is going quite well, especially after flipping off a fan.

The 33-year-old performer flipped off fans during his concert in Philadelphia after a female fan showed him her middle finger.

The singer stated, "You got second row to flip me the bird? That makes no f***ing sense."

As he stuck his middle finger to the crowd, the audience immediately reupted into applause.

Justin Timberlake will also be reuniting with Pharrell for the track "Brand New" for the Pharrell's new album "G I R L."
