Rihanna’s relationship with Justin Timberlake is strictly platonic and she wants Jessica Biel to know it! The umbrella girl had her assistant track down Jessica’s cell number and called her after rumors gained much attention about this romance between pop star Rihanna and Justin T. Rihanna told 7th Heaven actress that despite the gossip, JT is not bringing “SexyBack” with her!

Jessica’s 2 1/2 year romance with Justin is reportedly hanging by a thread, due in part to the former boy bander’s inability to commit.

“Rihanna doesn’t want to be pegged a homewrecker,” the Rihanna camp insider says. “She loves Justin, but only as a friend.”

While the two are collaborating with one another on Rihanna’s upcoming fourth album, the singer insists the relationship is strictly platonic.

“Rihanna apologized over the ridiculous nonsense that’s been printed. Rihanna has been cheated on in the past, and one thing she would never do is take another woman’s guy. Sure, she and Justin are close, he’s producing her CD.”

Jessica was on the Vancouver of her latest film, The A-Team, when she received Rihanna’s call. The girls chatted pleasantly and even agreed to get together for lunch, according to The Enquirer.

But wait! Rihanna and Chris Brown are planning a romantic getaway? They’re not supposed to see each other right? Well buzz is the young lovers have decided to jet to Acapulco, Mexico on vacay, as the ruling cannot be enforced outside the U.S.

“They spoke to their lawyers to see what was allowed, and are now planning two weeks in Mexico. They want to spend some quality time together and know they have a lot to reconcile before they can make their relationship public again,” says a spy.

“Rihanna’s desperate not to let her fans down as she’s had such support from them. She and Chris both need to have a long, hard think about a strategy that won’t hurt their careers.”

Oh Dear!
