Susan Sarandon Crashes Concert and Spanks Pigs On Stage!

Oh, and Solange Knowles also performed with them, and nobody cares.

Sorry, honey, Susan Sarandon stole your thunder!!

Okay. So we have no idea WHAT or WHY she is up there, but girlfriend knows how to get down, and we are LOOOVING it!

Last night indie rock band Of Montreal performed at the NYC Highland Ballroom, and Susan Sarandon, who apparently has pretty good taste in music, hopped on stage from the audience and proceeded to spank a bunch of guys in pig costumes!

Check out the HIGHlarious clip above!
