Looks like she's got the breakup blues!

Katy Perry touched down at LAX yesterday, and the singer covered her face with a pillow as she made her way to her car. The pop princess probably wanted to hide her distress over her her recent split with John Mayer, as it has been reported that they're "done for good."

The womanizing musician and the "Fireworks" songstress previously broke up because of their hectic schedules, but this time around the notorious lothario is simply over it! There was a "lack of emotional interest on his end" and he was telling friends he "fell out of love with Perry but will always love her," a source dished to E! Online.

Ouch!
