Although Kourtney Kardashian is living it up and having a great time with her rumored boyfriend Younes Bendjima, her ex, Scott Disick, seems to be taking the news of her new romance relatively hard.

Disick, who shares three children with Kardashian, has reportedly been indulging in heaving drinking since finding out that the star has moved on and friends believe he needs to go back to rehab, TMZ reported Thursday.

The star has been on a nonstop party train since finding out that Kardashian has been spending more time with the 24-year-old model.

Sources told the outlet that Disick believed he and Kardashian were going to eventually get back together since he quit drinking and started to treat her with respect.

On Monday, Disick visited Los Angeles hot spot The Peppermint Club for a fun night of drinking with friends. Prior to that, the reality star partied at TAO last Friday. These are just a few of the spots that Disick likes to hang out at since learning of Kardashian’s new romance. Sources say Disick also allegedly heavily drinks at his home while hosting parties.

News of Disick’s hard partying and heavy drinking comes days after Kardashian stepped out for a romantic birthday dinner with her model beau. The duo celebrated the model’s special day at IL Cielo, known for being one of the most romantic restaurants in Los Angeles.

The two spent three hours in the establishment where eyewitness revealed they were holding hands and kissing, according to E! News. When they left the restaurant, the two stuck close to one another’s side and were all smiles as they hopped into Bendjima’s Ferrari.

Although Disick seems devastated that Kardashian has a new boyfriend, he is reportedly dating 19-year-old model Ella Ross. The two have been spotted together on several occasions and on Tuesday, the reality star’s driver was seen giving Ross a ride following a night out on the town.

Even though it seems like Disick has moved on, his relationship with Ross is reportedly just a revenge romance. Sources told TMZ that dating Ross is Disick’s way of getting back at Kardashian for giving him false hope that they could get back together and be a family again.

The two split in July 2015 after Disick was photographed getting cozy with another woman.

Although his social life isn’t necessarily going great, DIsick’s career is thriving. The reality star recently landed a house flipping show that is going to be produced by Kardashian’s mother, Kris Jenner.

Sources have told the media outlet that there is no worry over Disick’s drinking when it comes to the series because the reality star has been drinking and managing his career for years.

As for Disick’s future, there is no telling what is next for the reality star. Only time will tell if he will pull his life together or continue down the path of destruction.
