Alcohol is a helluva boast juice. Over the weekend, Chris Brown used his Between the Sheets touring platform as a way to announce his separation with on-again off-again girlfriend, Karrueche Tran. After spouting “I’m single, f**k that b***h,” Chris and Tran go back and forth over social media – with Chris claiming Tran had a relationship with Drake and then some. The “Dangerous” singer in now apologizing (sobering up, clearly), but Karrueche is befriending a Mai Tai and not worrying about a damn thing. Hit the jump for more.
