Simon van Kempen (hubby of The Real Housewives of New York City's Alex McCord) performed his single "I Am Real" Thursday night on Bravo's Watch What Happens Live.

The reality star wore a tight black shirt and shiny purple pants as he sang -- and danced -- beneath a disco ball.

Host Andy Cohen laughed good-naturedly in the audience as Kempen sang: "I am real! I am who I am, that's the deal. I say what I feel! Love me or hate me, I don't give a damn."
