Lord, have mercy!

Scott Disick and Kourtney Kardashian celebrated Scott's 30th birthday in style at Bellagio's Hyde Nightclub in Las Vegas on Sunday.

The lavish couple looked ravishing during the royal bash. Scott wore a three-piece black tux to his party, while his longtime girlfriend dressed to impress in a black and navy blue feather-and-lace mini. The loving duo didn't bring their children Mason and Penelope, but invited family members Kris Jenner and Rob Kardashian.

Later in the night Scott jumped into the DJ booth to rap alongside DJ Reach to a remix of Rihanna's "Diamonds." Is there anything the Lord can't do?

And the frosting on the cake? Scott's regal birthday cake decorated with a life-size frosting tie and an elaborate jeweled crown, of course.
