Robin Thicke Suffers a Wardrobe Malfunction

"Blurred Lines" crooner accidentally showed off his bod when his shirt came undone during his iHeart Radio Music Festival performance

Robin Thicke kicked off the iHeart Radio Music Festival with a pop—literally.

The "Blurred Lines" singer suffered a wardrobe malfunction on Friday night when he hit the stage.

Robin showed more skin than he intended when a button on his shirt popped off, revealing Thicke's midriff. A photographer in the pit pointed out the mishap to Thicke, who then attempted to tuck in his shirt. 

But that wasn't the only wardrobe malfunction the singer endured.

Later during his performance, the singer's pants came partly unzipped! However, Thicke took the incident in stride, reportedly laughing off the moment with presenter Ryan Seacrest while wife Paula Patton and son Julian cheered him on backstage.
