EXCLUSIVE: Cameron Diaz, Glee's Matthew Morrison Rock Out Together

While rumored beau Alex Rodriguez licked his wounds after the Yankees' elimination, Cameron Diaz lived it up in Los Angeles on Saturday. RadarOnline.com has the latest details of her raucous night out.

At the two year anniversary of Bardot Hollywood presented by Jason Scoppa, Diaz and Joanna Garcia "sipped cocktails" and "jammed out" to Tom Petty covers and 30 Seconds to Mars- which is fronted by her ex Jared Leto- according to an onlooker.

Diaz, Garcia, and Morrison were fresh from a dinner at Soho House and enjoyed the live set from a booth right in front of the stage.

Ever the gentleman, Morrison drove the ladies home at the end of the night.

Morrison was "definitely feeling the live atmosphere," the onlooker said. The Glee star even cheered on some of the Session regulars like Macy Gray and LP.

Also there was Gene Simmons and his wife. The Kiss rocker looked on with pride as his son Nick took the stage to belt out Iggy Pop's The Passenger.
