Kanye West has urged Scott Disick to ''man up and go to rehab.''

The 38-year-old rapper, who has stepped in to help sister-in-law Kourtney Kardashian take care of her three children, Mason, five, Penelope, three, and seven-month-old Reign following her split from her long-term boyfriend, reportedly contacted the reality TV star, who has been struggling with alcohol issues and partying to excess recently, earlier this month and demanded he ''get his act together for the kids.''

A source close to the 'FourFiveSeconds' hitmaker: ''Kanye told him he needs to man up and go to rehab.''

The insider told Us Weekly magazine that Kanye was the one who advised the 'Keeping Up with the Kardashians' star to cancel his hosting gig at 1Oak nightclub in Las Vegas last weekend.

Following their heart-to-heart, Scott briefly checked into a rehab facility in Boca Raton, Florida on July 5, but he left after just six hours.

Kourtney, who is Kanye's wife Kim Kardashian West's older sister, dumped the 32-year-old star after nine years of dating after he was spotted canoodling with ex-girlfriend Chloe Bartoli in the South of France.

The brunette beauty's mother Kris Jenner is ''furious'' with Scott for his recent actions.

Another source told PEOPLE magazine: ''Kris is furious at Scott. He's just not seeing things clearly.

''First and foremost, Kris just wants to protect her family. Seeing her kids happy is the most important thing.''
