Posing semi-nude with Pettyfer, Hearst laughed off the reports which accused her as the cause of Pettyfer's split from 'Glee' actress Dianna Agron.
Lydia Hearst-Shaw has laughed off reports she sparked Alex Pettyfer's rumored break-up from Dianna Agron after posing for a sexy photoshoot with the British hunk.
The socialite-turned-actress stripped off to her bra for a risque series of shots with Pettyfer, in which the pair is shown kissing with another scantily-clad female model.
The recently emerged photos were said to have prompted Agron to call it quits with Pettyfer, but Hearst is adamant she shouldn't be blamed for the "I Am Number Four" co-stars' split - because the pictures were taken before they began dating.
She tells TMZ.com, "I can't help but laugh because it is nothing more than art, and it is beyond ridiculous that anyone would be upset about it. It was a kiss from over a year ago... it's time to move on."
