Actress Katherine Heigl has opened up about her feud with television writer-producer Shonda Rhimes in an interview with Mario Lopez, Extra TV reports.

Answering what she thinks about the comments made by her former boss about her, Heigl said: "The last one with Shonda... it sucks. I am sorry that she feels that way and I wish her nothing but greatness, and I have nothing negative to say about Shonda."

The actress admitted it's difficult to escape the negative image cast upon her but she's determined to prove it wrong.

"There's nothing I can do about it except to sort of prove it wrong," Heigl said. "And the only way to prove it wrong is for peple to have a work experience with me that doesn't speak to that at all."

In an interview with The Hollywood Reporter last month, Rhimes answered what it's like working with the cast of her new show "Scandal," saying: "There are no Heigls in this situation...no a**holes. I don't put up with bullshit or nasty people. I don't have time for it."

Earlier this month, Heigl participated in a Facebook Q&A and answered longstanding rumors about her work ethic and personality.

Addressing rumors saying she is "very rude," Heigl said: "Honestly, I don't think I am... nothing makes me more uncomfortable than confronation or hurting someone's feelings and I would never, ever actively do so on purpose."

Heigl started being branded as a person who's hard to work with when her relationship with the producers and writers of "Grey's Anatomy" started getting sour. It started when the actress said the part of the show where her character had an affair with a married man was a "ratings ploy" in an interview with Vanity Fair in 2008.

Things became more tense when Heigl asked to be removed from the 2008 Emmy race, citing a lack of material "to warrant [a] nomination," says The New York Times.
