Lady Gaga just delivered a powerful performance for a good friend.

Gaga took the stage at the 64th Grammy Awards on Sunday to deliver a tribute to her Love for Sale collaborator Tony Bennett.

Following a video intro by Bennett, 95, Gaga opened with a performance of "Love for Sale."

Originally a duet between the duo, Gaga took the stage alone and sang the sweet,

jazzy tune as she smiled and danced around in a strapless blue gown.

She then transitioned to the pair's song "Do I Love You," and as she sang the tune,

videos of her friendship with Bennett began to play in the background.

"I love you Tony, we miss you," she said after concluding the performance.

Gaga, 36, was nominated for five awards at this year's Grammys.She and Bennett won the award

for best traditional pop vocal album for Love for Sale, their second collaborative record.
