Jeff Bottari/WireImageHappy birthday, Scott Disick!
Kourtney Kardashian's beau rang in his 30th birthday at Hyde nightclub in Las Vegas on Sunday.
The fashionista couple definitely didn't disappoint on the red carpet for the birthday festivities.
Disick lived up to his Lord Disick nickname and looked polished in a tuxedo with a little bit of a grown-in beard.
Meanwhile, Kardashian was fabulous in a feather-and-lace frock. Who knew such an unexpected combo would be so sexy?
The mother of two flaunted her fit figure in the cocktail dress that showed off her toned gams and slim waist.
And while Mason and Penelope didn't attend the party, it looks like mommy and daddy finally got in some well-deserved couple's time.
You know what they say! What happens in Vegas...
