Justin Timberlake heading for a break up?

“He certainly didn’t look like a man with a girlfriend. He was partying in the upstairs VIP area with his best friend,Trace Ayala,Brett Ratner and a group of girls,” a source said.

“The girls were all over him,fighting to give him their numbers,and he seemed to be enjoying it.

There was one model-type blonde he chatted to for a while,” the source added.

The 28-year-old singer later left the place with the group of pretty girls in tow.

“Around 1:30 a.m.,Timberlake left along with Ayala,Ratner and a group of girls,including the model blonde,and headed to the Boom Boom Room,” the source said.

Timberlake had earlier broken up with Biel but agreed to take her back in his life on a condition that she is not allowed to talk about marriage and the couple put on a display of unity last month at a Jay-Z concert in Los Angeles.
