Frank Ocean has essentially been in hiding over the last couple of years, so when he popped up on Calvin Klein's Snapchat, it was a surprise to say the least. The brand announced the stars of its new campaign through the app, revealing that Young Thug would be a part of the ads as well, joining models like Kate Moss and Grace Coddington. 

Seeing that Frank recently hinted that his album would be out this month, this is certainly a good sign that he's ready to make his comeback. Check out a clip of the snap below, as well as some screenshots. Do you believe the rumors yet?
