0412-Bradley-Cooper-Suki-Waterhouse-Coachella-TWITTER-02Bradley Cooper got pretty cozy with ex-GF Suki Waterhouse Saturday at Coachella, and by the looks of it old habits die hard. 

Bradley and Suki were together for 2 years, until they split last month.  But it seems they were feeling the music.

Bradley also met up with Clint Eastwood, the director of his movie, "American Sniper" ... chowing down on pizza.
