if you were lady gaga wat song would you have sang at the grammy and with who???????????

I would have sung Poker face with cheryl cole, because this song is unforgetable! And it would have been an interesting mixture!

I would Have Sang Paparazzi Because it's a party Song! I Would Have Sang it With Jay Sean!

Iwould have sand Bad Romance and with whoever she wanted but I loved the duet of Sir Elton John! Besides the combination of Speechless and This Is your Song was A-M-A-Z-I-N-G!

i wud hav sang a song that every1 knew cos i didnt know wat she was singing somethin lke bad romance wud b good

paparoxie cuz its a awsome song

i would sing alejandro by lady gaga and with justin bieber.

I would definitely sing either Poker Face or Just Dance with Britney Spears or the Pussycat Dolls. Can't decide!
