Lance Armstrong's Daughter Takes Ashley Olsen for Show-and-Tell

Remember show-and-tell at school when you were a kid? When little boys and girls brought in things like dolls, rocks and pets?

Not to be outdone, Lance Armstrong's 6-year-old daughter Isabella (he has twins) reportedly brought dad's current playmate, 21-year-old Ashley Olsen to her Texas classroom for show-and-tell.

According to a source, "celebrities do this all the time" and Lance Armstrong himself was once toted along for show-and-tell by ex-girlfriend Tory Burch's son.

Huh?
