Usually when a star is accused of diva behaviour they laugh off the rumours.

That’s not the case with Katherine Heigl, however.

The actress, who has developed a reputation over the years for being a bit of a handful, has admitted that while she doesn’t think she’s rude, she has made “mistakes” in the past.

Speaking in a Facebook Q&A, the star said: “Of course, just like any human being, I’ve made mistakes and unwittingly or carelessly spoken or acted, but I always try to make any wrong right.”

She added: "That doesn't mean I won't stand up for myself by drawing boundaries and asking to be treated kindly and respectfully but I don't do that with any rude or unkind intentions just with the same strength and honestly I think every one of us is entitled to."

Heigl’s carefully-worded comments come just days after her former Grey’s Anatomy colleague Shonda Rhimes took a pretty big swipe at her.

The show’s creator hinted that there is no love lost between herself and the actress as she said: “There are no Heigls in this situation… I don't put up with bulls**t or nasty people. I don't have time for it.”
