Their stylist is going to be out of work soon!

Kourtney Kardashian celebrated a pal's birthday with a group of girlfriends at lunch in Calabasas yesterday, and the reality star rocked a red sweatsuit and Vans sneakers for the occasion. It seems nobody in the Kardashian clan can be bothered to get out of their pajamas these days!

The mother-of-three is the least interesting of the bunch, but she did just throw one hell of a birthday party for sons Mason and Reign. She posted a several pics from the soiree on her app Monday, and it was Fast & Furious themed! Even baby daddy Scott Disick was in attendance for the big bash, which was held in the backyard of her mansion.

She should really quit having flings with hot young boy toys like Justin Bieber and model Younes Bendjima and just get back with The Lord!
