Justin Timberlake is not hiding the fact that he is single and ready to mingle.  In fact - on the season finale of Saturday Night Live a couple weeks ago - Justin did a skit that poked fun at his,  somewhat reckless, womanizing tendencies.

On Monday night (May 30), Timberlake was spotted heading in to see a movie at a local theater with a mysterious female friend. The singer has been seen out and about with "Friends with Benefits" co-star Mila Kunis, or longtime friend Olivia Wilde -- but this mystery lady is a new addition to the group.

There has been no word yet on who the mystery woman is.
