Penn's got a new girl! Penn Badgley is dating Domino Kirke, the sister of Girls star Jemima Kirke, a source reveals exclusively to Us Weekly. The two were most recently spotted arm in arm in NYC on Wednesday, July 2.

"They've been dating for awhile. They have a number of mutual friends. It is a very mature and free relationship," a source tells Us. "Domino is a great girl for him, being a musician. Their interests align."

Badgley, 27, previously dated Zoe Kravitz, Lenny Kravitz's daughter, for two years until their split in June 2013. The pair shared an apartment together in NYC, and sparked rumors of a reconciliation during a PDA-filled getaway to Rome last September.

The musician-actor also dated his former Gossip Girl costar Blake Lively for three years before calling it quits in October 2010. Following her 2012 nuptials to Ryan Reynolds, Badgley admitted to Elle magazine that he didn't send his ex a wedding gift.
