The former Saved by the Bell star and his pals headed to the Pussycat Dolls Burlesque Saloon at the Planet Hollywood Resort on Saturday night (15Sep12) to check out the sexy revue - and Lopez was left open-mouthed when he saw Mazza step onstage in a skimpy outfit along with the rest of the dance troupe.
Mazza accessorised her black corset top and hotpants with long red gloves decorated with the words "I love Mario", and she took to her Twitter.com blog on Sunday to gush about the show, writing, "Last night I performed with the @pussycatdolls in las Vegas! It was amazing!".
Lopez and Mazza, parents to two-year-old daughter Gia, became engaged in January (12) after four years of dating. They plan to wed in Mexico later this year (12).
