« Pussycat Dolls Have Feelings, Too »

Hopefully this is NOT the O-Face of Nicole Scherzinger or her Pussycat Dolls.

Some singers are so emotionally invested in a particular song or performance that they actually break into tears while on-stage. Like Julio Iglesias and Fantasia.

Or Peter on the Brady Bunch. When he sang about his voice cracking. And finally growing pubes.
