This weekend keeping up with Kourtney Kardashian was a bit of a challenge, because in less than 24 hours she attended sister Kim's bridal shower, jetted to Houston to party with Scott Disick and jetted back to Los Angeles to celebrate Mother's Day with mom Kris Jenner. Whew!

Scott was celebrating his birthday at club Limelight, and he tweeted a sexy photo of himself all dressed up and wrote, "Doing my birthday big in Houston again, lots of surprises! ... Houston I'm suited and ready, @stickypromo u ready! Let's goo."

However, they must not have partied toooooo hard, because they were back in Los Angeles before 10am on Sunday. We can't imagine Kourt and her baby daddy would do Mother's Day brunch with a wicked hangover, but judging from the pic above, they looked pretty pooped!

Khloe was also spotted at the airport (and doing some late night Instagramming), so it seems like she was at Scott's bash as well:
