Penn Badgley and Zoe Kravitz have split.

The Gossip Girl star and Lenny Kravitz's daughter have called time on their two-year relationship but allegedly remain on amicable terms after their union came to a natural end. The 26-year-old hunk was first linked to the After Earth actress mid-2011, a year on from his split from on-and-off-screen love interest, Blake Lively.

"It is all good between them. It wasn't a sad breakup. It just wasn't working. It really did end on good terms, though," a source said.

Zoe has been working non-stop over the part year thanks to a blossoming film career. She will next appear in Mad Max: Fury Road alongside Charlize Theron and Tom Hardy, and is filming a big screen adaptation of Veronica Roth's teen novel Divergent in Chicago. Meanwhile, Penn recently wrapped production on Parts per Billion, co-starring Josh Hartnett and Rosario Dawson.

"They are at two different stages in their careers. They just didn't have time for each other," the insider added.
