Seyfriend: 'Lovelace' sex scenes 'a piece of cake'

Amanda Seyfried insists filming sex scenes for 'Lovelace' were a "piece of cake" compared to her erotic role in 'Chloe'.

The 27-year-old actress portrays porn star Linda Lovelace - who shot to fame after appearing in iconic 70s adult movie 'Deep Throat' - and had to shoot a number of sexual sequences with her co-star Peter Sarsgaard, who plays Linda's abusive husband Chuck Traynor.
