KATY PERRY CONGRATULATES EX-HUSBAND ON SOBRIETY

Katy Perry and Russell Brand split well over a year ago, but that doesn't mean that the former couple don't still support each other. According to The Sun, the "Firework" singer, 28, reached out to Brand, 37, via email to congratulate him on 10 years of sobriety.

"10 years clean today. Thanks for all your messages of love... Anyone can get clean, one day at a time," Brand tweeted on Dec. 13.
