Rumor has it a racy photo shoot was the cause of Alex Pettyfer and 'Glee' diva Dianna Agron's breakup. Last year, Pettyfer stepped into a whole new world for a daring photo shoot with celebrity photographer Tyler Shields, but during the shoot, the 'I Am Number Four' actor got a little too close for comfort with models Lydia Hearst and Leven Rambin. Apparently, even though the two weren't dating at the time, Agron was more than a little upset by the racy photos.

PopEater was able to chat with Shields to get his take on the shoot and the breakup.

"I'm really not sure how the shoot could have caused the breakup, but if it did, it was totally not intentional," Shields told PopEater. "When people come to shoot with me, they know what they're getting into, and if they don't, they learn very quickly. Also, the people I shoot are actors. They were directed totally by me, and they were acting. We must have done too good of a job if people thought it was that real."
