If Lindsay Lohan ever gets married she has someone to dance — wildly — at her wedding.
Her uncle Paul Anthony Sullivan, 56, stole the show at an otherwise stuffy Hamptons wing-ding Saturday night.
“You have to see this guy,” chirped Margo Catsimatidis, “he’s incredible.”
Soon, a crowd at the Southampton Hospital annual gala gathered and a portion of the dance floor opened up as the brother of Dina Lohan did splits, cha-chas and squats that could “easily land him on ‘Dancing With the Stars,’ ” said one amused onlooker.
Others watching nearby included Rita Cosby, Joy Marks, Lauren Buccellatti, Stephanie Clark and emcee Chuck Scarborough.
Afterward, a sweat-drenched Anthony told us, “I’m soaked, but I had fun.”
