Lea Michele Not So Nice at Coachella

Glee starlet hits desert music fest with her costars but makes fun of a fellow concertgoer

A few Glee stars ditched New Directions this weekend and hit Coachella in the desert to watch other people sing for once.

Lea Michele, Chord Overstreet and Harry Shum Jr. all checked out the concerts together from the VIP area Saturday, where one of them was trying to go incognito.

"Harry introduced himself to two girls as Jerry from San Luis Obispo and said he was unemployed," an eyewitness reports. "The girls played along even though they knew who he was."

But when one girl jokingly called "Jerry" over to sit with them later, Lea couldn't resist making fun of her...

"Lea started laughing and imitated her in a high-pitched voice," the onlooker said. "She was totally mocking her for no reason."

Lea was all smiles later while hanging at the Lacoste and HTC pool party on Sunday, where Katy Perry, Kellan Lutz and Alexander Skarsgård were also spotted.

Chord and Harry ditched Lea later and caught up with another Gleek at the Armani Exchange Neon Carnival Saturday night. They hit the late night bash with Mark Salling.

Also enjoying games, rides and dancing at the bash into the early a.m. was Leonardo DiCaprio, Rihanna, Ashley Greene, Vanessa Hudgens and Paris Hilton.
