Kelly Clarkson nearly "died" from embarrassment when she got President Obama's name wrong.
The 'Breakaway' hitmaker first met the US leader at an event when he was just a junior senator but was left red faced when she stumbled over his name.
Speaking on Late Night with Seth Meyers, she said: "I get up there, complete panic sets in because I can't remember what that fake Grammy is called, I can't remember what the book is because it had just come out ... And I can't remember his name, but I am pretty sure it rhymes with 'sama'.
"I completely butchered it, I literally had the mic, after I just nailed it, and I'm like ... [mumbles nonsensical words]. I swear to God, I wanted to die. I wanted to fall down and pretend I had a stroke - I would've faked some horrible thing."
And the 34-year-old singer is not the only celebrity to be left embarrassed following a meeting with the world leader.
Blake Lively recalled: "I met Obama and I had my whole speech planned. He was introducing himself to everyone and they were talking about the way that they were gonna change the world. He came to me and I was just like 'I ... Hope!' It was just like me summoning hope for myself, it was awful.
"The only thing I could think of was that he'd left my husband a voicemail when he was running for president. So I said, 'You left my husband a voicemail!' And he was like, '...Cool!' And I said, 'And he deleted it!' It was just like, why did I say that? It got worse! I was like, 'He deleted it cause you were just a senator then!' And then I was like, 'That was bad.' So I was like, 'Well, he didn't know you would be president. I mean, who thought that ... you would ... be pres ... ummm ... Can you leave my husband a voicemail?' It was just getting worse."
