After catapulting her star to new heights at last year's MTV Video Music Awards, Lady Gaga is once again the headline-maker at the 2010 show. From the moment she stepped onto our specially designed white carpet, flanked by four very special guests, she lit up the Internet, photographers' flashbulbs and the critical eyes of the fashion community.

When she stopped by MTV's pre-show to chat with Sway, she had already received the first two awards of the evening: Best Dance Video for "Bad Romance" and Best Collaboration for "Telephone" with Beyoncé.

"Thank you so much," she said, adding a shout-out to Beyoncé. "We did it Honey B!"

Regarding how many outfits she plans to wear tonight, Gaga told Sway that we'll have to watch and see. "You'll just have to find out," she teased. "But this dress is Alexander McQueen, from his last collection."

Speaking to her four special guests, the "Bad Romance" singer explained that she is here not only because of her 13 nominations, but for an important cause.

"I'm here for a very, very important cause tonight," she said. "These are all my friends and they are with SLDN.org, which is an organization that was founded in 1993 under the reaction to the 'Don't Ask, Don't Tell' policies. Their stories are very inspiring and there's so much we can do right now."

Gaga went on to say that her four guests were all discharged from the armed forces or opted to leave their services on their own.

"No one person is more valuable than another person," she concluded.
