Johnny Depp, Amber Heard a new item?

MAX NASH/GETTY IMAGESJohnny Depp and Amber Heard, who co-starred in 2011's "The Rum Diary," are reportedly dating.

Johnny Depp recently revealed he'd split from his longtime partner, Vanessa Paradis. His "The Rum Diary" co-star Amber Heard has reportedly broken up with her girlfriend, the photographer Tasya van Ree. The tabloids have done the math: (2-1) + (2-1) = 2!

Depp and Heard are "100 percent dating," a source proclaims to Usmagazine.com. Though they met on the set of "The Rum Diary" in 2009 -- the year before Heard came out as gay (or, depending on which story you read, bisexual) -- they didn't start seeing each other until the 2011 promotional tour, when, the magazine says, Depp and Paradis were already seriously estranged.

Rumors that Depp and Paradis, who have two children together, were on the outs started circulating in December, but they didn't confirm their split until last week. (In fact, Depp actively denied any trouble with Paradis.)
