Video: Stars Come Out for the ‘Very Important’ Macy’s Passport Presents Glamorama Event

ET has new video of Mark Salling and other big name stars eager to give back at the Macy's Passport Presents Glamorama Event, which combined music, fashion and charity.

"This is a very important event," said Los Angeles Mayor Antonio Villaraigosa. "Fashion is important to Los Angeles and this is a great cause." The cause of the event, held Thursday, September 16, was to raise funds and awareness for HIV/AIDS organizations.

"The biggest element of tonight that I am in love with is the charity element, giving back to the different charities that this is focusing on," Aubrey O'Day told us on the red carpet. "Especially, for me, the AIDS charities."
