SAY WHAT??!!

Both the New York Daily News and the New York Post are reporting that Lance Armstrong hooked up with Ashley Olsen on Monday night.

The odd were seen "canoodling" and "nuzzling" at New York's Gramercy Park Hotel.

"They came together with a group of friends," says the Post. "Ashley drank red wine, sat on his lap and they were making out all night. They left together around 2 a.m."

She's 21. He's 36.
