Rebel Wilson has taken to Twitter to apologise after she claimed to be the first ever plus-sized woman to lead a romantic comedy.

The Australian actress stars in the upcoming meta rom-com Isn't It Romantic, in which her leading character, Natalie, becomes trapped in a romantic comedy.

While talking about the film on The Ellen DeGeneres Show, Wilson sparked controversy when she said: "I'm proud to be the first-ever plus-sized girl to be the star of a romantic comedy."

Commentators took to Twitter to point out that actresses such as Mo-Nique and Queen Latifah have paved the way before her, but Wilson refused to be corrected, questioning whether "technically those actresses were plus size".

Monique subsequently tweeted Wilson, asking her not to allow this business "to erase our talent with giving grey areas and technicalities" and urged her to "take a moment and know the history".

On Tuesday, Wilson backtracked on her comments, writing: "In a couple of well-intentioned moments, hoping to lift my fellow plus-sized women up, I neglected to show the proper respect to those who climbed this mountain before me like Mo'Nique, Queen Latifah, Melissa McCarthy, Ricki Lake and likely many others."

She continued: "With the help of some very compassionate and well-thought out responses from others on social media, I now realize what I said was not only wrong but also incredibly hurtful. To be part of a problem I was hoping I was helping makes it that much more embarrassing & hard to acknowledge."

The Pitch Perfect star went on to apologise for blocking people on Twitter who criticised her original comments.

"I blocked people on Twitter because I was hurting from the criticism, but those are the people I actually need to hear from more, not less. Again, I am deeply sorry," she wrote.

Isn't It Romantic, in which Wilson stars alongside Liam Hemsworth, is scheduled for release on Valentine's Day next year.
