Justin Timberlake and Olivia Wilde hit the Roxbury in Los Angles on Saturday night.

The pair are two of Hollywood’s newest singletons and partied until the early hours of the morning.

Last month Timberlake announced his split from his girlfriend of four years, Jessica Biel. Wilde announced in early March that she and her husband were filing for divorce after eight years together.

The two actors are currently co-starring in “Now”.

The pair arrived at the club together and were both dressed casually in T-shirts and jeans and reportedly left together at 3am.

One source told that: "they happened to meet each other there. They weren't on a date. They've been friends since they worked together on Alpha Dog. Nothing's going on. They're just friends."

Their film collaboration sees a world where the aging gene has been switched off and to avoid over population, time has become the currency.  It is due to be released September 20, 2011.
