The Bad Romance star appeared on stage as her male alter-ego,
whom she has called Joe Calderone, smoking and ranting at the
audience.
At first, celebrities including Britney Spears appeared bemused as
to the identity of the person on stage, but later rejoiced when
Gaga began to sing.
Moments later, she was joined on stage by Queen guitarist Brian
May for a rousing performance. Watch the video below.
The singer, whose real name is Stefani Joanne Angelina Germanotta,
was nominated for - and won - the Best Female Video accolade for
her smash-hit Born This Way.
Remaining in character for the entire show, Gaga's Calderone later
presented Britney Spears with her lifetime achievement award and
even accepting her own award "on behalf of Gaga."
