Reminiscent of Janet Jackson, Idina Menzel almost had a Janet Jackson like wardrobe malfunction onstage a Radio City Music Hall during Monday night's performance.

She handled it flawlessly.  She cracked jokes about the accident even saying, "That's gonna be all over TV".  She also said a word you didn't hear in Frozen.

Menzel was wearing a leather bra-type top under a beautiful dress.  The front of the dress was open.  Let's just say the bra-type top rode up...her assistant had to come on stage and help.  Note the video is uncensored.
