Mario Lopez Skips Charity Event to Party with Playboy Bunnies

Oye, Mario, shame on you. Perez Hilton reports that sort-of celebrity Mario Lopez decided to bail on his benefit-hosting duties for Casas Seguras, a charity to help victims of domestic violence and their children, in his hometown of Chula Vista on October 27, opting instead to party toda la noche at the Playboy mansion.

While Mario bared his butt-cheeks and partied with the likes of Paris and Nicky Hilton, organizers of the annual charity event were left disappointed and disgruntled. They had been promoting the event—and Mario's attendance— for months!

His official excuse for standing up the charity? The local fires that have displaced his family members! We know at least one thing that's en fuego...Mario's pantalones.
