Vermonter Jerry Seinfeld's party

Jerry Seinfeld’s daughter is all grown up, says the New York Post.

Sascha Seinfeld celebrated her 21st birthday with a 1920s-inspired soirée on Sunday.

“Our Sascha Seinfeld turns 21 today,” the comedian’s wife, Jessica Sklar Seinfeld, wrote in a post to Instagram. “We had the best weekend celebrating this phenomenal human being, along with her friends, who love her almost as much as we do. ”

The birthday girl’s mom went on to gush about how special her daughter is, writing, “She works hard, she plays hard, and in between, makes life better for everyone in her orbit. ”

The Seinfelds own a multi-million-dollar lakefront mansion in Vermont's largest city.

Jerry's wife grew up in Burlington and graduated from the University of Vermont.
