Sascha’s mother, Jessica Seinfeld, paid tribute to her daughter in a post containing photos from the epic bash on her Instagram account.

The birthday girl couldn’t have looked any happier as she posed with her friends, whom were all decked out in head-to-toe flapper gear.

And it wasn’t Sascha’s friends who were present, but her whole family, with Jerry, Jessica, and their two other children, sons Shepherd, 16, and Julian, 18, joining in the fun.

Despite being one of the biggest celebrities on the planet, Jerry appeared to have a more reserved presence as he sat back watching the festivities unfold with his wife.

Though they weren’t the center of attention, the couple still couldn’t contain their delight.  

‘We are parents of a 21-year-old!’ Jessica gushed as she shared a silly photo of them at the party.

‘Our (angel emoji) Sascha Seinfeld turns 21 today. We had the best weekend celebrating this phenomenal human being, along with her friends, who love her almost as much as we do,’ Jessica captioned the post on Instagram.
