Adele just proved that even Grammy winners can have off days when performing in front of thousands of adoring fans.
The 27-year-old was in the middle of belting out her hit 'A Million Years Ago' at her show in Lisbon, Portugal last week when she suddenly stopped mid song.
"S--t, wrong words, s--t, s--t, s--t!" she said as the crowd erupted in laughter.
"I started singing the verse not the chorus – sorry!"
Adele, who is currently on the European leg of her world tour, won big at the Billboard Music Awards earlier this week, taking home five awards including the Top Artist Award, Top Billboard 200 Album, Top Female Artist, Top Billboard 200 Artist and Top Selling Song.
The ‘Hello’ singer also premiered the video for her latest single ‘Send My Love (To Your New Lover)’ off her new album ‘25’ at the show.
