Lance Armstrong was reportedly advised to ditch Ashley Olsen when the pair briefly dated back in 2007, according to "Cycle of Lies," a new tell-all book.
John Korioth, head of Armstrong's Livestrong Foundation, "warned the 36-year-old father of three that his May-December romance could damage his cancer work," Julie Macur writes in the book. "'Whoa, dude, bad idea,' Korioth said. 'You've got to put a stop to this right now.'"
Armstrong apparently didn't appreciate the relationship advice. "She's 21," he reportedly responded. "F-- you." But the relationship fizzled out after a few months anyway, with Armstrong moving on to Kate Hudson.
