It's the big 5-0 for President Obama and he's celebrating in style with an exclusive party in Chicago.
But if you want an invite, expect to pay! The party at Chicago's Aragon Ballroom is actually a fundraiser for next year's presidential race and tickets are selling for up to $35,000!
Obama is just the third president to turn 50 in office; Teddy Roosevelt and Bill Clinton also turned 50 while serving as Commander-in-Chief.
So how's the President holding up? Well in some ways, he's showing his age. President Obama's hair has gone almost completely gray since he took office three years ago.
"It's very common for the President of the United States to experience fatigue and stress, which can really take a toll on their appearance and I think you've seen this with President Obama," said presidential historian Jane Hampton Cook.
President Obama doesn't seem to mind getting older. He says Michelle told him she still thinks he's 'cute' and that that's all that matters.
Who else is turning 50 this year? George Clooney, Meg Ryan, Eddie Murphy, Heather Locklear, Michael J. Fox, and one of the President's harshest critics—conservative author Ann Coulter!
