Maria Menounos may have just turned 35, but she sure doesn't look it -- and it's no surprise the "Extra" host made sure to show off her killer body in a bikini at her luau-themed birthday party.

The birthday girl documented every moment of the celebration from getting her hair done, to her pre-pool party, and the actual big event on Saturday night:

"My pre pool party was so fun I am wasted am trying to get sober for my real party at 8!!!! Ahhhhhhh!!!," she wrote on Twitter, later adding: "Over 50 people showering and getting ready in my house right now! So fun!!"

All that preparation and pre-partying must have been worth it since Menounos tweeted:

"You know it's a good party when people are still dancing at 3 am!!! Woohoo!!"
