Scott Disick -- Bails on UK Club Gigs at the Last Minute ... Via Twitter

Scott Disick continues to piss people off all over the U.K. -- this time by bailing on two club appearances at the very last minute ... and the clubs only found out by checking Twitter.

Disick was supposed to appear at Southampton's Switch night club and Bournemouth’s Cameo club, but instead jetted off to Paris to hang at Fashion Week with Kim Kardashian, Kanye West, Kris Jenner and Kendall Jenner.

Switch night club blasted him, saying ... "Scott Disick has let us know via his manager's Twitter at 9.30pm that he cannot come tonight due to 'unforeseen circumstances.' The real truth is he's gone to Paris to party and ignore his fans."

Switch continued, "These famous for nothing celebs have too much money and don't realise [sic] they are letting down venues, ruining peoples reputations and livelihood, and their fans."

Disick has two more club appearances scheduled in the U.K. for Friday night -- and both clubs say Disick's people have assured them he'll be back from Paris in time.

Disick is already in hot water for his behavior at an appearance earlier this week. The organizers plan to sue him, claiming his poor attitude and general disinterest cost them a lot of money.
