Holly Madison and Benji Madden: Moon Party Pals

They’re always up for a good time and last night (April 6) Holly Madison and Benji Madden were spotted at the Moon nightclub at the Palms Resort Casino.

The “Girls Next Door” babe looked excited as she supported the Good Charlotte rocker, who was manning the deejay booth.

Earlier in the day, Holly announced Mayor Goodman’s proclamation of “Serendipity 3 Day” in honor of the one year anniversary of Serendipity 3 at Caesars Palace.

Miss Madison was super sexy in a strapless pink princess dress teamed with a pair of pale pink heels and a pink flower in her platinum blonde hair.

Enjoy the pictures of Holly Madison and Benji Madden at Moon and of Holly at Caesars Palace Resort and Casino earlier in the day (April 6).
