Singer Chris Brown and Long Island-born reality TV star Scott Disick reportedly have bonded as friends and each other’s sober-support system.

TMZ.com said Sunday that Brown, 26, and Disick, 32, originally of Eastport, are saying they drank only water when they went together to the nightclub 1OAK some days ago. Each is a father, and maintaining a cordial relationship with the children’s mothers appears to be a motivating factor, TMZ said.

Since summer, Disick has been estranged from his longtime partner, Kourtney Kardashian, of the Kardashian reality show clan. The two have three children: Sons Mason, 6, and Reign, 1, and daughter Penelope, 3.

Disick’s history of alcohol abuse played out on last year’s Kardashian series “Kourtney & Khloé Take the Hamptons,” which saw Disick enter Connecticut’s Mountainside Treatment Center after a night of partying. As well, said TMZ at the time, Disick’s binging at a Hamptons nightclub that June 22 made him sick enough to believe he might have been drugged. He was admitted to the Southampton Hospital emergency room, where doctors diagnosed him with alcohol poisoning, the site said.

Brown, who was convicted of felony domestic violence in 2009 after attacking his girlfriend at the time, singer Rihanna, has had recurring high-profile anger incidents. He has a 1-year-old daughter, Royalty, from a relationship with a former model TMZ on Sunday called Mia Guzman, but whom E! and other outlets give as Nia Guzman or Nia Gonzalez, and whose Facebook and Twitter pages give as Nia Amey and Nia Gonzalez.
