"Holly's World" star Angel Porrino is staying busy as the "The Weather Girl" in the popular Las Vegas cabaret show "Absinthe." But this past Friday, the reality star took some time out to judge a hilarious "naughty schoolgirl" costume contest at Posh Nightclub in Las Vegas.

She then provided Fox411 with her criteria for the perfect costume.

"It needs to be short enough because it's a naughty schoolgirl competition," Porrin said. "It's gotta be pretty naughty to win me over."

Porrino, dressed in a sexy schoolgirl outfit herself that included a tiny red plaid skirt, a black bra with red lace and leather boots, also gave us her dream celebrity naughty schoolgirl.

"Mila Kunis," said Porrino. "She's probably my girl crush. She's amazingly hot. Her eyes are beautiful. I just…I just would like to see her anything!"

Porrino's cabaret show "Absinthe" is a part of the "Spiegelworld" outdoor carnival experience located at the Caesars Palace Hotel and Casino in Las Vegas.
