VIDEO : You've Never Seen Aubrey Plaza Like This Before - in a Bikini!

We've been treated to a lot of sexy behind-the-scenes photos from the set of Dirty Grandpa recently, but so far, they've all been of a shirtless Zac Efron (not like we're complaining). But this week, pictures surfaced of a bikini-clad Aubrey Plaza filming scenes with Robert De Niro , and we have to admit: we never thought we'd see this side of her! The actress, who is best known for playing the surly April Ludgate on Parks and Recreation , showed off her impressive frame in a bright blue two-piece while shooting scenes with Robert, Zoey Deutch, and Zac, who stayed shaded from the sun under an umbrella.??
