Seth Rogen has blasted his 'Knocked Up' co-star Katherine Heigl's latest film.

The comic actor - who, along with director Judd Apatow, was upset when Katherine claimed 'Knocked Up' "painted women as shrews" while making the men look "loveable" - has questioned the portrayal of the sexes in her new movie 'The Ugly Truth'.

Speaking on a US radio station, Seth said: "That film looks like it really puts women on a pedestal in a beautiful way!"

Judd added: "I hear there's a scene where she's wearing underwear with a vibrator in it, so I'd have to see if that was uplifting for women."

Revealing he still feels hurt by Katherine's comments, Judd said: "You think at some point I'll get a call saying, 'Sorry, I was tired,' and then the call never comes."

Seth takes comfort in the fact Katherine has made other rash comments since blasting 'Knocked Up'.

He said: "I've got to say it's not like we're the only people she said some bad s**t crazy things about. That's kind of her bag now."

Judd also said he didn't understand Katherine's actions because she was very involved with making the film with him at the time, even improvising her own lines.

He said: "Seth always says, it doesn't make any sense because she improvised half her s**t. At the time, on set, she could not have been cooler."
