It was one of the biggest moments of Grammys, as Beck collected his award and walked up to the microphone, somebody else approached the stage: none other than Kanye West.
The audience gasped and jeered in horror – could they be about to witness a repeat performance of one of the most cringeworthy moments in award ceremony history?
As reported by the Telegraph, Kanye famously interrupted Taylor Swift when she beat Beyoncé at the MTV Video Music Awards in 2009, shouting: "Yo, Taylor, I'm really happy for you and I'mma let you finish, but Beyoncé had one of the best videos of all time. One of the best videos of all time!"
Luckily, Kanye thought better of stealing Beck's thunder and quickly jumped down, indicating that he may have been poking fun at himself – but not before prompting guffaws from Beyoncé and Jay Z.
Beck seemed as surprised as the rest of the audience when he won the award Sunday and appeared to be looking around for help.
Recording academy president Neil Portnow said the almost-Kanye moment was part of the excitement of a live television show.
"It's unpredictable," he said. "You don't know what's going to happen. ... That turned out to be a fun moment at the end of the day."
But footage of the rapper filmed at a Grammys after-party suggests that he might not have been joking after all.

"If the Grammys want real artists to keep coming back, they need to stop playing with us," he told E! Television's After Party show.
"Beck needs to respect artistry and he should have given his award to Beyoncé, and at this point, we're tired of it.
"Because what happens is, when you keep on diminishing art and not respecting the craft and smacking people in the face after they deliver monumental feats of music, you're disrespectful to inspiration."
He added that he had decided not to say anything on stage because, "I got my wife, my daughter and my clothing line, so I'm not going to do nothing to put my daughter at risk," but insisted that it was his job to "fight for creativity".
