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 [1] (not like we're complaining). But this week, pictures surfaced of a bikini-clad Aubrey Plaza filming scenes with Robert De Niro [2], 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. It was announced back in January [3] that Aubrey would be starring as a popular party girl in the Spring Break comedy, and filming has been happening [4] over the past couple weeks around Tybee Island, GA. Keep reading to see Aubrey's impressive bikini body, and look back on Aubrey's best moments as April Ludgate [5].
