The one thing that Mean Girls taught us is that Halloween is the one night a year when a girl can slut it up!
Not that we're saying that Jenny McCarthy is a slut, but she certainly is one sexy kitten and we can't take our eyes off of her.
The fiiiiine blonde bombshell steamed up the red carpet at Planet Hollywood's Gallery Nightclub in Sin City on Wednesday night dressed as the purrfect pretty kitty kat.
All she had to do was accessorize her lovely lace lingerie with some ears, a cat mask, and a tail! Halloween costume = complete!
We bet she clawed some hearts out last night!
Just take a looksie of more pics of her (below)!
