Agron and Pettyfer co-star in I Am Number Four, a movie about an alien refugee on Earth that is being hunted by other aliens. The two stars began dating last summer while shooting the film together. However, Agron and Pettyfer reportedly broke up this past week just in time for the film's opening.
According to TMZ, Agron left Pettyfer over a photo shoot that took place early last year, months before the pair started dating.
In the pictures, which were only recently released, Pettyfer can be seen half-naked with models Lydia Hearst and Leven Rambin.
Agron is yet to issue a statement on the report.
