Scott Disick has reportedly been in a ''dark place'' since his parents' death.

The 31-year-old star, whose mother Bonnie Disick died from an illness in November and father Jeffrey Disick passed away suddenly in January, has allegedly grown distant from his pregnant girlfriend Kourtney Kardashian and her friends are worried he is partying too much.

A source told In Touch Weekly magazine: ''He's in a really dark place and Kourtney knows it. He hasn't been dealing well with his parents' deaths. He has no family left except her. She constantly tries to help him, but Scott pushes her away or numbs everything with partying.''

The 'Keeping Up with the Kardashians' star, who also has son Mason, four, and daughter, Penelope, 23 months, with Scott, has been warned by her friends to stop enabling her long-time partner.

But the insider added: ''Trying to change him is exhausting. At this point, he's been a mess for so long that she should know he'll never change.''
