Pettyfer dating Elvis’ granddaughter?

I Am Number Four star Pettyfer is currently shooting new film Magic Mike with Lisa Marie Presley’s daughter Keough – and it appears the pair has become more than just co-stars and friends.

The couple was spotted at the Los Angeles International Airport and a source tells, “They looked really cute together, cuddling and kissing each other before boarding their flight. They seem to be enjoying their new relationship.”

Pettyfer has previously dated Glee star Dianna Agron and Emma Roberts. Keough’s exes have included pop star Ryan Cabrera.
