Taraji P. Henson thought Maroon 5 performed the Super Bowl halftime show.
The 'Empire' actress got confused between the 'Moves Like Jagger' hitmakers and Coldplay - who actually provided the entertainment at the NFL Championship Game yesterday (07.02.16) - when she tweeted about how much she was enjoying their set.
She wrote: "YAAAAAAASSSSSS!!!! #maroon5 is life to me!!! #superbowl50#HappyCamper I am.(sic)"
After thousands of fans pointed out her error, Taraji - who was at the sporting spectacular at the Levi's Stadium in Santa Clara, California - deleted her tweet.
She posted instead: "Oooooooopppps. Lmao! (sic)"
But the 45-year-old star insisted she wasn't the only one who thought she was watching Maroon 5, as the fellow guests in her suite all agreed with her.
And Taraji also admitted when she first got messages about her tweet, she thought it was just people upset she hadn't praised Beyoncé, who, along with Bruno Mars and Mark Ronson, also joined the group on stage.
She told 'Entertainment Tonight': "Angie Martinez, Mary J. Blige, my cousins, my mother, my grandmother - everybody's texting me, 'change your post!'
"I [thought] they're mad because I didn't give homage to Beyoncé! I'm like, 'The Beyoncé post is coming!' Then I realised it was Coldplay."
The 'Curious Case of Benjamin Button' actress blamed the gaffe on mixing her drinks.
She said: "I don't know if you know how it goes down in the suites.
"They put a lot of drinks in there - Kool-Aid, lemonade, iced tea. I mixed it all and I sat there and I'm sitting with people who drank the Kool-Aid as well."
