Ashley Olsen dated Lance Armstrong until his handlers told him to end it, new book claims

NEW YORK, March 9 (UPI) -- Lance Armstrong and Ashley Olsen dated briefly back in 2007, when witnesses saw them "making out all night" at the Gramercy Park Hotel in New York City. She was 21 at the time, while he was 36.

Armstrong, who confessed to doping last year, has done plenty of damage to his career in the intervening years. But at the time, his friends and handlers were more worried about his dating life.

According to Cycle of Lies: The Fall of Lance Armstrong, a tell-all book written by New York Times columnist Juliet Macur, Livestrong Foundation chief John Korioth "warned" the former cyclist that a relationship with the former child star could "damage his cancer work."

"Whoa, dude, bad idea. You've got to put a stop to this right now," Korioth allegedly said.

"She's 21…f**k you," Armstrong hit back.

Macur's book, which hit shelves last week, details the rise and fall of the former athlete.
