Lady Gaga "cried" because she was so overwhelmed at singing with Sir Elton John.

The 23-year-old singer was so happy the pair got to perform a spectacularly extravagant duet - seated either side of a giant piano which sprouted hands - at the Grammy Awards on Sunday (31.01.10) she was forced to make an emergency visit to her make-up artist shortly before she was due on stage.

"I ruined all of my make-up right before the show. Crying... I was just so happy."

The 'Bad Romance' hitmaker picked up two awards at the event - Best Electronic/Dance Album for 'The Fame' and Best Electronica/Dance Song for 'Poker Face' - and dedicated her wins to her legion of fans.

She told 'Access Hollywood': "This is not an award for me, it's for my fans. And I love my fans so much. And I wanted them to know that they should believe in themselves.

"And I wanted to be everything that they hoped I would be tonight, and that's what we got to do."
