That's one impressive starting lineup!

The morning after his $40,000-a-plate fundraiser for President Barack Obama--which he hosted at his L.A. home--George Clooney hit the basketball court with the leader of the free world.

The Ides of March star's girlfriend Stacy Keibler opened up to Us Weekly Saturday at the 19th Annual EIF Revlon Run/Walk For Women about what it was like watching Clooney shoot hoops with the president.

"I got to watch them play basketball," Keibler, 32, told Us. "It was something I'll never forget."

Adding that she "was a cheerleader on the side," the actress says she lucked out and ended up not having to choose who to root for.

Explained Keibler, "George and Obama were on the same team, so they both [won] . . .It made it easy!"

Clooney's Thursday fundraiser is said to have raked in an estimated $15 million for Obama, who made headlines this week with his public support for the legalization of gay marriage.

"We raised a lot of money because everybody loves George," the Commander-in-Chief, 50, told the crowd of his actor pal. "They like me, they love him. And rightfully so."
