If Justin Timberlake and Olivia Wilde aren’t dating, they’re sure playing the roles of a couple like two seasoned actors.

Timberlake brought Wilde to an event last night in New York at the restaurant he co-created: Southern Hospitality. The popular BBQ spot hosted a birthday party for the restaurant’s owner, Eytan Sugarman. The owner’s actual birthday was last month, but with Timberlake in New York this week to host “Saturday Night Live,” they delayed the party in part so the pop star could attend.

A person that was inside the Hell’s Kitchen location tells “The Ralphie Radio Show” that Timberlake and Wilde were in the back of Southern Hospitality having dinner. “He had his arm around her the whole time,” the witness recalled.

As Timberlake and Wilde walked to a private lounge where more celebrities were hanging out, it was apparent to on-goers that the two are an item.

Wilde and her husband Tao Ruspoli announced they were separating in February. Timberlake and former girlfriend Jessica Biel allegedly split last March, after four years together.
