MUMBAI: Pop star Chris Brown and reality TV star Scott Disick are reportedly encouraging each other to stay sober and have only been drinking water when they are out clubbing.

They have been spending a lot of time together lately, ever since Disick appeared in Brown’s music video for ‘Picture Me Rollin’ and although they have been spotted at nightclubs, neither of them is drinking, reports tmz.com.

A source told the website that during a visit to 1OAK nightclub, Los Angeles last week, they only drank water and they are helping each other to “stay strong and sober.”

Disick, who split from Kourtney Kardashian earlier this year, recently spent time in rehab, while Brown has reportedly vowed to give up partying for the sake of his daughter Royalty, whose mother is his former love interest Nia Guzman.
