Justin Timberlake & Olivia Wilde shares cozy night out !

Justin Timberlake and Olivia Wilde fueled the romance rumors this weekend after they were seen getting cozy at L.A. hotspot Roxbury.

Sources told Us Weekly magazine that the pair were “dancing all night” at the club.

“They were dancing, whispering, he had his hand on her back and shoulders and they were together all night.

“His arm was around her, they were talking closely, just the two of them…Justin and Olivia were there with a group, but weren’t talking to anyone else.”

Timberlake split from girlfriend Jessica Biel last month after over four years together, while Wilde filed for divorce from hubby Tao Ruspoli after eight years of marriage March 11.

Meanwhile, a source told PopEater that Timberlake and Wilde are just good pals.

“Justin and Olivia became close working together on ‘Now.’ They are both newly single and both want to get out and have fun with friends, but they are not an item,” said one insider.

“Justin and Olivia just wanted to have some fun. But it wasn’t romantic.”
