I Am Number Four star Alex Pettyfer is showing why she should be #1 in this sexy photo by famed photographer Tyler Shields. Nice chiseled chest!

The photo shoot, featuring models Leven Rambin and Lydia Hearst-Shaw biting the 20-year-old actor's ear, reportedly ended Pettyfer's relationship with Glee actress Dianna Agron who wasn't happy with the kinky spread.

The sexy couple, who lived together in Los Angeles, began dating last August. As for the photos, they were snapped in early 2010, which makes you wonder why Agron would care since the shots were taken before they were dating.

A picture is worth a thousand words and two of those words are apparently ... it's over.

See Mr. Pettyfer in action ... after the jump.
