They split in July 2012 after Kristen was spotted locking lips with director Rupert Sanders.
After they split, though, their characters were still an item, which Penn recently admitted was a little weird.While appearing on Bravo’s “Watch What Happens Live,” the 28-year-old “Cymbeline” star was asked about his best on-screen kiss. In our opinion, though, Penn’s admission is actually kind of a compliment to Blake.I get to do things nobody would ever say or do in real life."Leighton, 23, says the nonstop scrutiny doesn't bother her.That seems impossible, but after watching her closely, we believe her.But that's not to say she's always a homebody — cast members often go out together, and Leighton's been written up in New York gossip columns for "downing tequila shots" and making out with abandon at nightclubs.

As you can see, she donned oversized shorts and a drapey silk cardigan and platforms at a fashionable Maybelline New York event.
