Here’s newly married (boooooo!) Jennifer Aniston climbing some stairs and doing some stretches and prancing around on the set of her new movie Mother’s Day wearing a pair of workout leggings that are doing one hell of a job of convincing us that she still has one of the sexiest bodies around, and inducing a drool-fest thanks to her awesome booty… wowzers! This girl is forty-six years old! What the hell is she still doing with an amazing body like that!? Oh yeah, and she’s also busting out some plentiful cleavage and unleashing her killer legs, but it’s her booty that’s making me squirm in my seat today. So enjoy the photos and check out the rest after the jump!
