Lady Gaga Rocks Out With Mark Ronson For Rousing Grammys Performance Of 'Shallow': Watch

There could be 100 people in a room, but there's only one Lady Gaga. The ever-evolving talent overtook the Grammys stage Sunday night (Feb. 10) with a rollicking performance of -- what else? -- "Shallow," her hit duet off box office smash A Star Is Born with co-star Bradley Cooper.   

Cooper was notably absent tonight, instead attending the BAFTAs in the U.K. But Gaga -- or should we say, Ally -- held her own, kicking and hair-flipping her way across the stage in a sparkly skin-tight bodysuit and chunky sky-high platforms that harkened back to her The Fame era. Her mic and mic stand? Also bedazzled.

She was joined onstage by the song's co-writers, Anthony Rossomando, Andrew Wyatt and Mark Ronson, and yes, she belted out the track's signature "AaaaaAHAHHH" howl with as much passion as ever.  

Gaga already raked in two Grammys tonight for the tear-jerking love song -- best pop duo/group performance and best song written for visual media. She also earned best pop solo performance for “Joanne (Where Do You Think You’re Goin’?).” 

The beloved ballad, which Gaga has been performing during her Enigma Las Vegas tour, is making a mark on awards season. At the BAFTA Awards, Gaga, Cooper and Lukas Nelson were awarded best original music for the song. It has already won a Golden Globe and Critics' Choice award, and later this month, it will compete for the Oscar for best original song.
