Ashley Greene isn't ready to let go of summer just yet! The Twilight actress turned up the heat on Staten Island on the set of her upcoming film Staten Island Summer at the Great Kills Swim Club on Monday, Sept. 9.

Greene, 26, showed off her toned (and tanned!) bikini body in nothing but a teeny tiny pair of yellow bikini bottoms, opting to go topless as she soaked in some rays. Costars Vincent Pastore and Graham Phillips were also spotted on set.

The film, about a few friends who decide to take on jobs as lifeguards while they figure out what to do with their lives, will be produced by Saturday Night Live creator Lorne Michaels.

"Being sexy is about intrigue and mystery -- not putting everything out on the table," Greene once told Men's Fitness.

Earlier this month, Greene took advantage of her temporary residence in NYC, exploring the city and even popping by the U.S. Open on Saturday, Aug. 31.

"New York I LOVE you," she tweeted, along with a photo of city gridlock from the backseat of a cab. "Traffic I STRONGLY DISLIKE you."
