Lady Gaga & Justin Timberlake Perform On SNL (VIDEO)

Just when we thought we seen Lady Gaga do it all.... she stunned TV viewers in America on Saturday night. Not only did she do some funny skits with JT.... she donned a prosthetic baby belly and climbed into a prop delivery room chair during a live performance of hit single Born This Way.

The pop performance artist was the musical guest on the season finale of Saturday Night Live when she left fans scratching their heads with another odd routine.

Towards the end of the tune, the superstar hid behind her dancers, strapped on the belly and was lifted into a birthing chair, complete with stirrups. To add to the wacky routine, her leather-clad dancers then showered Gaga with gold paint.
