Joe Biden got Taylor Swift and Britney Spears mixed up in an awkward gaffe on his 81st birthday.
The US President made the remarks while pardoning two turkeys, Liberty and Bell, in what is an annual Thanksgiving tradition.
He used the name 'Britney' in a comment which appeared to be referring to Taylor Swift.
Biden, who turned 81 yesterday, said: "Just to get here, Liberty and Bell had to beat some tough odds and competition.

"They had to work hard, to show patience, and be willing to travel over 1,000 miles.
"You could say it's even harder than getting a ticket to the Renaissance tour or, or Britney's tour.
"She's down, it's kind of warm in Brazil right now."
Spears is not currently on tour, while Swift is in the middle of a string of international dates.
She postponed her concert in Rio on Saturday due to extreme heat.
Joe Biden has faced mounting criticism in recent months for a number of awkward gaffes during public appearances.
Earlier this year, Peggy Grande, former long-term adviser to Ronald Reagan, told GB News that the White House is taking a "basement strategy" approach - keeping him out of the public eye.
She noted that "the more he's been in the public eye the lower he drops in the polls".
When asked if this is going to increase as time goes on, she said: "Yes. We’ve seen it increasingly I’ve the last six months to a year.

"We've seen major cognitive decline with the President. His physical capacities are much more limited."
She added: "They're trying to cover for him and they're going to keep limiting his public appearances".
When asked about Biden's birthday, White House communications director Ben LaBolt chose to focus on Biden’s accomplishments rather than his age.
He said: "Because of President Biden’s decades of experience in public service and deep relationships with leaders in Congress, he passed legislation that has helped to create more than 14 million jobs, lower prescription drug costs, invest in America’s infrastructure and technology and led to the strongest economic recovery in the developed world,” LaBolt said.
“He has revitalized alliances on the world stage — cultivated over many years — to promote America’s interests and respond forcefully when global crises arise".
