The enduring and enduringly unlikely pairing of Tony Bennett and Lady Gaga performed the title track of their 2014 collaboration album Cheek to Cheek on the Grammys. Singing in the round, the sparkly-dressed Gaga sang the opening lines, "Heaven, I'm in Heaven," while coming around the piano to Bennett. When the crooner piped in, he barked the same line, the jazz music kicked up and Gaga began dancing. They then danced together for the instrumental break.
The album Cheek to Cheek had been nominated for only one award for Best Traditional Pop Vocal Album. Between the pair, though, they have accumulated 23 Grammys, with Bennett snagging 17 (including a whopping 11 for Best Traditional Pop Vocal only) and Gaga grabbing six for her debut The Fame (and subsequent deluxe edition The Fame Monster).
Gaga's last performance at the ceremony was in 2011, when she emerged from an egg to sing "Born This Way." The year before, she opened the show by performing "Poker Face" followed by a mash-up of her single "Speechless" with Elton John's "Your Song," who joined the British singer-songwriter.
Bennett's last Grammy appearance was a performance of "It Had to Be You" with country singer Carrie Underwood in support of his nominated album Duets II. The album was the first to feature a collaboration between Bennett and Gaga: their duet on the Rodgers & Hart classic "The Lady Is a Tramp."
Gaga has never hidden her superfan status and mentee appreciation when it comes to Bennett, and the pop star has had her own chance recently to act in a mentor role for fellow nominee Sam Smith. Following his reveal that he once got detention for skipping class to see Gaga in his Rolling Stone cover story, Gaga offered some words of wisdom. "Continue to suffer for your art," she offered to Smith. "But don't allow anyone around you who is not putting your talent and happiness first."
