Clad in a white one-piece and gold heels, Molinaro, a recording artist, put on a show at Sin City's Piranha nightclub -- and the men in attendance had all ears and eyes on the brunette stunner.
Her performance was part of the club's celebration of its fifth anniversary.
And she had a special guest in the audience.
"love my Brother!!!" Molinaro tweeted after the gig. "It was amazing having him here & watching me perform tonight!!"
Melissa Molinaro is also dating Kim Kardashian's ex-boyfriend, NFL star Reggie Bush.
