Justin Bieber's performance at the 2026 Grammy Awards was stripped down in more ways than one. The singer, 31, went shirtless while hitting the stage to perform his hit single "Yukon" on Sunday, February 1, at the Crypto.com Arena in Los Angeles. Bieber showed off his chest tattoos as he took the microphone with the spotlight right over him, opting to wear only silver boxers and black tube socks as he strummed on a purple guitar. "What would I do (What would I do?) / If I didn't love you, babe?" he crooned. "What would I do if I didn't love you, babe?" Hailey Bieber.
