Johnny Depp Officially Off the Market?

Is Johnny Depp headed down the aisle for the first time? Galpal Amber Heard has been spotted with what appears to be a diamond ring on a certain finger, E! reports, and all the gossip outlets are murmuring that the pair might be engaged. Rumors about Heard, 27, and Depp, 50, have been flying since last year, but until recently they had only been pictured together in an unofficial capacity. That changed Saturday, when they walked the red carpet as a couple at an art gala in LA. But Heard was back to acting private Monday night, apparently doing her best to hide the ring when she was spotted. (More Johnny Depp stories.)
