Is it ever a good thing when Scott Disick is your sisters' chaperone?
On Tuesday night, Scott escorted Kendall and Kylie Jenner to an LA fashion show and a party at a club afterwards, but his behavior makes it seem like he's the youngest one of the group.
During the Day by Day fashion show, the 30-year-old was reportedly being "drunk and rude the whole night." One model even appeared to flip him off and Scott tried to pull the designer down off stage during curtain call.
Then after the show, he was caught on camera rapping and ranting with Lil' Twist.
"I drive f*cking Bentleys!" Scott screams as Kendall and Kylie look on. "This is so embarrassing," one of the girls can be heard saying.
The rowdy group's next stop was Vignette, a 21-and-over club, which is illegal, considering Kendall and Kylie are only 17 and 16.
We don't think Scott's girlfriend Kourtney Kardashian or the girls' mom Kris Jenner is going to be happy about this!
