Dianna Agron Kisses a Mystery Man, Leonardo DiCaprio Dances the Night Away and More Coachella Sightings

DiCaprio and Agron weren't the only celebs having a blast at Coachella this weekend. Get the scoop, right here!

Dianna Agron was not shy about packing on the PDA at Coachella this weekend.

The Glee star gave a big smooch to a mystery man at the famed music fest Saturday in Rancho Mirage, Calif., lip locking in clear view at the McDonald's & Stingray Desert Pool Party.

According to Just Jared, her kissing partner was none other than actor Thomas Cocquerel, who was last linked to Lily Collins back in February.

"Arches in the sky. Thinking about Cheeseburger Sundays Kev," Agron tweeted Saturday during the event.

And she wasn't the only star having a blast.

Leonardo DiCaprio was also at the McDonald's party, smoking an electronic cigarette, and chowing down on a Bacon Clubhouse Burger and fries in his private cabana. Then as the sun started to set, the Wolf of Wall Street star slapped on a face mask (of sorts) and danced around the party with a male friend.

Pretty Little Liars stars Ashley Benson, Shay Mitchell and Troian Bellisario also made an appearance there, hardly leaving each other's sides throughout the event.

Meanwhile, Nina Dobrev rode into the party on a motorcycle with a mystery man, rocking denim short overalls, and Kendall Jenner was also there sipping on a McCafe Mango Pineapple Smoothie in her private cabana.

At the Lacoste Beautiful Desert Pool Party Saturday, Katy Perry was hanging out in a private cabana by the pool, wearing printed shorts, a white top and a pink hat.

Meanwhile, Jared Leto, Kellan Lutz, Kelly Osbourne, Joe Jonas and his girlfriend Blanda Eggenschwiler, Aaron Paul and his wife Lauren and Steven Tylerwere just some of the celebs spotted partying at the NYLON & Olay Fresh Effects present Neon Carnival with GUESS Saturday. The Oscar winner was also spotted taking photos with the new GS5 and checking out Milk Music at the VIP Samsung Galaxy Lounge at the Carnival along with Osbourne, Diddy and Carmen Electra.
