Reese Witherspoon [1]'s daughter, 18-year-old Ava Phillippe [2], may be a spitting image of her mom, but turns out, Reese has another twin [3]: her body double Marilee Lessley. Reese first met Marilee on the set of Legally Blonde 2, and she's been her body double in five movies now. On Monday, Reese finally introduced her to the world via Instagram [4]. "I want to introduce you to someone who has been working with me for years," Reese said in a video. "This is Marilee and she's my double. Don't we look alike?" If we didn't know any better, we'd guess these two were twins.
