Despite reports that Justin Timberlake and Jessica Biel’s two-year relationship is over, sources tell People the couple has not broken up.

In fact, on Monday night they were photographed together while on a getaway in Northern California.

“They’re together,” says an insider. “They’re not breaking up. Any time they spend time apart it’s because they’re working.”

Over the summer, Timberlake, 28, was in Europe promoting his Givenchy fragrance and William Rast clothing line, while Biel, 27, remained in Los Angeles where she starred in Guys and Dolls.

But in January, the actress plans to climb Mt. Kilimanjaro (as part of the star-studded Summit on the Summit expedition to raise awareness for clean water), and Timberlake, says sources, is in talks to join her.

Whether the couple will still be together in three months is another story.

According to a second source, they are going through a rough-patch.

“Things have been a bit up in the air recently,” says the source.

“They’ve been spending more time apart — more time with each of their friends, and they’ve been reevaluating (their relationship).”

As for rumours that Timberlake has been getting close to Rihanna, a source close to her insists that the relationship is purely professional: “They’re working together. They were in the studio for her album and they’ll be going back in again.”
