The 26-year-old singer promised his followers "something special" for Martin Luther King, Jr., Day before sharing a link to his "Who's Gonna (Nobody)" remix featuring Keith Sweat.
Brown and Keith Sweat co-wrote the original song, which appears on the singer's seventh studio album, Royalty. The record debuted at No. 3 on the Billboard 200 in December, and also includes the singles "Liquor" and "Zero."
Disick shares three children with Jenner's half-sister Kourtney Kardashian, from whom he split in July after nine years of dating. The reality star experienced suicidal thoughts after the breakup, as seen on Sunday's emotional episode of "Keeping Up."
"Contemplating dark thoughts should be taken very seriously," Kardashian's sister Khloe Kardashian tweeted in response to the episode. "It was a terrifying situation but sadly I'm great in those situations. Wish no one experienced them."
Brown and Disick reportedly share mutual friends, including Khloe Kardashian's ex-boyfriend French Montana, and have developed their own friendship in recent months.
The pair visited the Ace of Diamonds strip club after leaving The Nice Guy in the same car, according to TMZ.
