Alex Cooper wears $8,000 crystal look by Stella McCartney for 30th birthday

Alex Cooper is 30, flirtatious and definitely successful.

Fresh from the news of their multimillion-dollar deal with SiriusXM, the Call her daddy The presenter headed east to celebrate her 30th birthday in Montauk, New York.

For the weekend party, which kicked off on August 23, Cooper wore several looks, including a rhinestone-embellished outfit by Stella McCartney.

Her bejeweled Adam suit consisted of a $6,500 plunging nude bodysuit embellished with glass beads and crystals. She paired the one-piece with matching micro-mini hot pants (also Stella McCartney), which are now sold out, and white lace-up stilettos.

Cooper also hosted an end-of-summer party attended by her husband Matt Kaplan and their famous friends – including Love Island USA Runners-up Leah Kateb and Miguel Harichi as well as former Bachelor Candidate Maria Georgas – and even some of her fans!

The festivities took place at The Breakers Motel, where Cooper hosted Unwell’s Motel 30 event in white hot pants under a sheer floral lace dress and oval sunglasses by Otra.

“The Daddy Gang completely took over Motel 30 and let me tell you, it was so much fun,” Cooper said in an exclusive statement to PEOPLE. “We lived our best lives in Montauk this weekend – eating, dancing and of course belting out Taylor Swift songs at the top of our lungs.”
