Here are a few things to know about the pair:

They announced they were a couple shortly after James' divorce was finalized from Sandra Bullock, whom he split from after it was discovered he'd had multiple affairs, which all came to light following Bullock's 2010 best actress Oscar win for The Blind Side. As scientists have pointed out, there is an actual correlation between winners of the best actress Oscar and divorce.
