Lady Gaga kicked off Grammy night with a fiery performance - Elton John joined the outrageous singer on stage for a duet after she was thrown into a pit of flames. (See the video and the rest of her latest outrageous outfit after the jump!)

The singer took to the stage solo for a high-energy rendition of Poker Face at the beginning of the show and ended the performance with dancers tossing her into fake fire.

She then stunned fans by re-emerging back onstage seated at a piano across from the Rocket Man.

The colorful pair, whose outfits and faces were smudged with ash, played and sang each others' hits "Speechless", and "Your Song", as they looked at each other from the joined pianos.

Gaga made sure she paid tribute to her idol before the performance was over - smiling at him from her seat she added a lyric to "Speechless": "Thank you, love you, Sir Elton John. So speechless."
