There's been a mysterious air around Johnny Depp [1] and Amber Heard's relationship since they were first linked in 2012 — even Amber's quotes about their marriage [2] are slightly cryptic — but one thing is clear: these two had some insane chemistry. Even before they tied the knot in a secret ceremony [3] in February 2015, Johnny and Amber were showing sexy PDA and bringing the heat at public events. Unfortunately, news broke on Wednesday that Amber reportedly filed for divorce from Johnny [4] and while details are scarce, sources say the actress cited irreconcilable differences in her petition. Look back at their sweetest moments together, then take a look at all the couples who have already called it quits this year [5].
