Actress claims standing up for herself makes her a ‘b*tch’.

It certainly seems like Katherine Heigl is more famous for her diva reputation than her acting roles these days.

The thirty-six-year-old former Grey's Anatomy star certainly spends a lot of her time defending herself against people who claim she’s difficult to work with.

Last week, we seemed to see a softer side to the Knocked Up star when, in an interview with Mario Lopez, she appeared to extend an olive branch to former colleague Shonda Rhimes, who has made no secret of the fact she considers Katherine ‘a nasty person’.

It looks, however, as if Katherine is done trying to reach out to people and instead hotly denies the numerous claims that she’s rude and unprofessional.

Speaking out on The Meredith Vieira Show, she said: “We should all have the basic human right to say, ‘Hey, no I’m sorry. I’m not comfortable with that. I don’t like that. This is not okay for me.’ Without it making me… I can’t say the word…a b-word.”

Commenting on her diva reputation, the stunning blonde said: “I’m not. I’ve been saying I don’t think I am, but I’m just going to be really honest now. I’m not. I know I’m not.”

Well, that’s us told then!
