Strutting down the red carpet in a divine looking one-shoulder black and white gown by Armani Prive, Gaga, 35, had all eyes on her as she entered the building.

Paying homage to old Hollywood glamour, Gaga looked expensive as she flaunted her beauty in the jaw-dropping open-back gown that included a sweeping white train.

The 12-time award-winning Grammy performer finished the look with a retro updo that showed off her dazzling jewellery by Tifanny and Co.

The hit-maker and her close friend Tony Bennett, 95, are nominated for five awards, including album of the year for their collaborative album Love for Sale.

After her epic red-carpet entrance, Gaga did not stop there as she dazzled the audience with her melodic renditions of Love for Sale and Do I Love You from her album with Tony.

After Tony introduced her via a video message featured on the big screen at the ceremony, Gaga ascended to the stage in a glamorous mint green gown.CrossoutCrossout 2.0: Superchargedby TaboolaGaga’s old Hollywood ensemble had everyone talking (Image: Getty Images for The Recording A)Lady Gaga looked sensational at this year’s Grammys (Image: Broadimage/REX/Shutterstock)

The pop-jazz fusion singer received a standing ovation from the audience.

She dedicated the performance to Tony, saying after the song: “I love you, Tony, we miss you.”
