mattsettlediv.jpg Not only is Gossip Girl's Matthew Settle planning to divorce his wife Naama Nativ, but he's already stepping out with other women!

A source for Us Weekly reports that "divorce is imminent," and the actor was spotted flirting with a mystery lady at club SL in NYC the day before Valentine's Day. Additionally, his wedding ring was off during fashion shows on February 11 and 12 in Bryant Park, so it looks like he's already moved on.

The source added, "The marriage was difficult for him. His priority now is his daughter." And finding someone new?
