Kevin Winter/WireImageLady Gaga and Tony Bennett really jazzed up the 2015 Grammy Awards!
The 28-year-old singer and the 88-year-old legend teamed up to sing their duet "Cheek to Cheek" during Sunday night's big awards show. The stellar performance even had the entire audience jumping to their feet to applaud!
Gaga wowed in a strapless va-va-voom black dress that showed off lots of cleavage. She paired her sparkly dress with a gigantic diamond necklace and Jessica Rabbit-inspired waves in her white hair. After starting the number off with her powerhouse vocals, Gaga danced up on Bennett as they did their adorable duet in front of a piano and band.
Once they finished crooning the hit jazz ballad, Bennett yelled to the audience, "Thank you!" "Ladies and gentlemen, Mr. Tony Bennett!" Gaga added as the crowd stood up for a standing ovation. After their super-star performance, they shared a sweet kiss on the cheek. Too cute.
Earlier in the night, Gaga and Bennett walked the red carpet together and looked adorable while posing for pics. They also chatted with E! News about their unlikely friendship. "We get along great, we're both Italian Americans," Bennett said. "We understand one another."
"She's a great artist," he added.
They also gushed about their pre-Grammy Awards win for Best Traditional Pop Vocal Album for their album Cheek to Cheek. "We're so happy! So, so happy," Gaga gushed.
