Yesterday was Day 1 of the Lacoste Beautiful Desert Pool Party where guests and celebrities alike mingled at a private estate near Palm Springs.

Lacoste, the lifestyle brand built on its genuine sporting roots, hosted its annual chic pool party in celebration of one of the most stylish festivals in the country.  Lacoste created a fun escape and desert oasis for the 5th consecutive year.  Lacoste brought its new brand platform “Life is a Beautiful Sport” to life at the event with various on-site complimentary activations and amenities.

Attendees included: Katy Perry, Lea Michele, Jonathan Groff, Steven Tyler, Emma Roberts, Evan Peters, Miles Teller, Mark Salling, Kesha, Jena Malone, Logan Lerman, Alexandra Daddario, Ryan Philippe, Lana Del Rey, Victor Cruz, Ari Graynor, Haim, Holland Roden, Max Carver, Riley Keough, Sean Faris, Laura Vandervoort, Chvrches, Aluna Frances of AlunaGeorge, and Dillon Francis. Performances by DJs Elijah Wood, Johnny Wujek, Nikki Pennie, and DJ Skee.

Katy Perry ran into music legend Steven Tyler poolside and things got interesting when he took a bite of her hat. Miles Teller was captain of the dance floor in his festival get up, shimmying around his girlfriend while she laughed. Lea Michele brought best friend Jonathan Groff to socialize and lounge in the cabana as she caught up with Glee co-star Mark Salling and shared some girl time with Katy Perry. Julianne Hough kept her festival look casual in a Lacoste tank top with baggy jean shorts and seemed relaxed as she laughed with friends.
