The fashion brand alice + olivia by Stacey Bendet is celebrating its 20th anniversary and some big stars stepped out to help ring in the occasion!

Lea Michele and Ariana DeBose were in attendance at the anniversary party on Wednesday night (June 15) at the Close East Lawn in New York City.

Inside the party, Lea was seen catching up with her friend Busy Philipps and Ariana checked out some of the fun activations, including the basketball court.

Also in attendance was Nicky Hilton, who is pregnant with her third child.

Lea and Ariana were both in attendance at the Tonys this past weekend. Ariana hosted the event and Lea reunited with her Spring Awakening cast members for a performance to celebrate the show’s 15th anniversary.
