Lady Gaga Ain't Bluffin' With Her ... Button?

Whatever the heck that thing is on Lady Gaga's head, seems to be just as big as her heart.

Pop sensation, Lady Gaga, and her button head thing made a surprise visit to Orange RockCorps volunteers in Manchester, England, on Monday (June 30).

Around 50 volunteers were working their butts off at Body Positive North West (a center in South Manchester that helps and supports people living with and affected by HIV and AIDS) for four hours to score a ticket to see Lady Gaga perform at the Manchester Apollo on July 13.

RockCorps is basically a way to give back to your community for four hours in exchange for a killer concert ticket — "You can't win a ticket; you can't buy a ticket; you have to earn a ticket."

Everyone went totally gaga. "They were so cute they didn't know I was coming so they all were like 'that chick looks like Lady Gaga, oh my God it is Lady Gaga!,'" she told the Telegraph. Gaga also confessed how the AIDS charity reflects her personal life, "I have a lot of gay and lesbian friends who are confronted by the fears of that sort of lifestyle ... I am a loving person that believes in the power of spreading that love to people."

Despite her album titled, The Fame, she doesn't let it go to her head ... except for maybe a giant button.
