J.K. Rowling has been criticized by numerous celebrities for implying that women are the only ones who menstruate in a recent tweet, and now former "Harry Potter" stars like Daniel Radcliffe are condemning the author.

Rowling tweeted out a link to an article about creating a more equal world for people who menstruate on June 6, and included a controversial opinion about the phrasing, saying, "'People who menstruate.' I'm sure there used to be a word for those people. Someone help me out. Wumben? Wimpund? Woomud?"

Numerous users called out the post for being transphobic, pointing out that trans men can menstruate, as can gender non-conforming and non-binary people.

They also pointed out that it erased the lived experiences of women who don't menstruate, which can be the result of things like menopause or health conditions like endometriosis.

Unsurprisingly, plenty of people, including celebrities like Jameela Jamil and Jonathan Van Ness, denounced the "Harry Potter" author's controversial statements and offered their support for the trans community. And now, stars of the "Harry Potter" movies (and the series' spin-off play) are speaking out, too.

Here are five "Harry Potter" stars who have condemned Rowling for her problematic comments.
