Engagement season isn’t over just yet — and it looks like another celebrity couple may have just joined the pre-nuptial pack! After a rare public appearance together last Golden Globes weekend, Johnny Depp, 50, and his girlfriend Amber Heard, 27, are causing buzz that they have plans to walk down the aisle after Amber was spotted wearing a ring on that finger this week.

While leaving a restaurant in L.A. Monday night, the Paranoia actress was snapped with a giant rock on her ring finger (click the link below to see the snap). Soon after, she seemingly realized that the diamond had been seen, and attempted to cover it up with her other hand (photo at left). A little too late, lady!

Though nothing has been confirmed, it seems pretty suspect that Amber would work so hard to cover it up if it was nothing. The two, who met on the set of The Rum Diaries in 2011 have been (publicly) dating for over a year and a half, but until now we’ve seen very little of them together in the press.

We’re a little surprised that Johnny would be ready to jump back into marriage after his 2012 divorce from wife of 14 years, Vanessa Paradis. However, Amber is clearly a  beautiful woman and they are admirably private about their relationship, so hey, maybe this is the real deal!
