Hot hookup alert! Scream 4 star Emma Roberts, 20, and Glee's Chord Overstreet, 22, were spotted kissing up a storm at the A/X Armani Exchange and 944 Magazine carnival at the Coachella Valley Music Festival this weekend, according to a eyewitnesses.

A fellow reveler tells X17online: "Emma and Chord were really going at it. They looked like two kids, having a fun night out, letting themselves go, and really getting into each other."

Could this be a new couple? Will they continue their romance now that they're back in LA and back to work?

We caught Ms. Roberts at the hair salon yesterday -- appearing to have gone a little lighter. Maybe a new look for a hot date with Chord?!
