The 31-year-old reality TV star, who previously insisted he was planning to go back to the Rhythmia Life Advancement Centre in Costa Rica after only spending a week there in March, has reportedly informed his longtime girlfriend Kourtney Kardashian "that he has his drinking under control."

A source close to the 'Keeping Up with the Kardashians' star, said: "Scott told Kourtney and the rest of the Kardashians that he does not want to go back to rehab. He thinks that he has his drinking under control."

The former restauranteur was hospitalised for alcohol poisoning last June and his struggle to stay sober has been frequently documented on the E! reality series.

He spent a week in rehab in March and said at the time: "I realise my issues are bigger than me and I'm ready to truly remedy this struggle I continue to battle."

The insider also told gossip website RadarOnline.com: "Kourtney is just so beyond it that she almost doesn't even care what he does anymore."

But the 36-year-old beauty, who has three children, Mason, five, Penelope, two and Reign, four months, with Scott, recently claimed her family is "stronger" than ever.
