Young (and hot!) Hollywood showed up in droves last night for “Red is for Emmy” party for Invisible Children at the King King nightclub in Hollywood. The OC’s Benjamin McKenzie (I know you need to know that he wears Calvin Klein underwear) presided as host of the party for the media-based non-profit, Invisible Children which premiered the third installment for a bracelet campaign - “Emmy: The Story of an Orphan.” Who else was on the guest list? The OC’s Adam Brody and Autumn Reeser, Veronica Mars‘ Kristen Bell, Ryan Hansen, and Jason Dohring, Lost’s Ian Somerhalder, and Desperate Housewives‘ Josh Henderson. Ryan is too cool for school and Ian needs a haircut… stat!

Josh Henderson (best known for dating Ashlee Simpson on The Ashlee Simpson Show) debuted his abs last night on Desperate Houseives, playing Edie’s bad boy nephew, Austin Britt. Watch the Josh Henderson shirtless scene below and check out the screencaps in the gallery!

QUESTION :: How did Josh measure up as the new hunk on Wisteria Lane? Or do you prefer gardener John’s manboobs (Jesse Metcalfe)?
