Heigl 'regrets calling 'Knocked Up' sexist'

Katherine Heigl has regretted revealing that the movie Knocked Up was sexist, it has been reported.

Director Judd Apatow and co-star Seth Rogen recently appeared on The Howard Stern Show and disclosed their disappointment with the actress.

The Ugly Truth star, who has acknowledged that she is prone to putting her foot in her mouth, has mentioned in an interview that she should have thought twice before commenting on the 2007 hit comedy.

Heigl told Marie Claire: "If I was to say I wish I'd never made that comment about Knocked Up being sexist, it's not that I don't feel the way I do about it, it's just that it maybe didn't need to be communicated via a magazine interview."
