Khloe Kardashian has a new, innocent crush -- and he's a Nobel Prize winner!

On Wednesday, the reality star blogged about her Jan. 25 trip to the White House; Kardashian, 25, escorted husband Lamar Odom and the L.A. Lakers, invited by President Barack Obama to celebrate their 2009 NBA Championship. (Team captain Kobe Bryant presented Obama with a Lakers jersey.)

"I was lucky enough to tag along LOL," Kardashian explains. In an instantly famous photo that circulated the day of her visit, she shook hands with the President as he greeted players' wives and girlfriends.

"Never did I EVER think I would be in the same room as the president, let alone get to shake his hand," she gushes.

"I was pretty nervous but I think I held it together pretty well. President Obama was so sweet and charming...I might have had a slight crush on him LOL!!"

The star's blog post features 30 new photos -- the team posing with Obama, and plenty of interior details -- which she snapped during her tour of the manse and presidential grounds. "I went a little camera crazy while there," she admitted. "I was seriously such a tourist!
