Talk about handling the ex-factor well! The Hills star Audrina Patridge crossed paths with ex-boyfriend Justin Bobby at Hollywood hot spot Les Deux Wednesday night, engaging in a few laughs and friendly conversation. Avoiding the drama that her MTV reality series is known for, Audrina, who split with Justin last year, was seen vying for her former beau’s attention for most of the night, says an observer.

“She was trying to get his attention, talking and touching his arm,” says the witness. “They did not seem awkward at all with each other.”

Could they be rekindling their romance? During the reunion, Audrina definitely enjoyed Justin’s presence. “She was trying hard to get him to stay next to her and occasionally she succeeded,” our spy says. “They laughed and shared looks at each other’s phone a couple times and it seemed to make Audrina really happy.”

But the feeling may have not been mutual. Says the observer: “He didn’t seem as interested in talking to her as she was with him. Justin just went on with his night and didn’t seem phased by her presence.” –Christina Tapper
