Not only did Jessica Simpson look absolutely amazing last night when she took the stage at NYC's Madison Square Garden, she was in great spirits!

Dressed in a LBD, Jess joked with the audience about her recent weight gain and all the publicity she's been getting from it.

"I've had times when my pants split right down the middle when I bent down to reach a note," the singer told fans, laughing.

"That's why I'm wearing a skort - not a skirt, not a short - just so they wouldn't split."

After her 35 minute performance Jessica was spotted with her beau Tony Romo at a mid town bar with some friends.

Judging by how sexy she looked onstage last night, now more than ever we know it was those mom jeans that made her look so full last month.
