It looks like there might be a new Hollywood catfight between Amal Clooney and Cindy Crawford. Even though their husbands George Clooney and Rande Gerber are best friends, the two women apparently have had a hard time getting along with each other and now there's a report that says things have gotten even worse between them.

According to Celebrity Dirty Laundry on Sunday, sources say that the British Human Rights Lawyer allegedly mocked Cindy Crawford by comparing her to transgender reality television star Caitlyn Jenner. And of course, Cindy was having none of it.

A source says that when Caitlyn's Vanity Fair cover came out last summer, Amal pointed out that she looked very much like Cindy, who apparently took the comment more as an insult than a compliment.

The insider said, "She doesn't ever want to be mistaken for Caitlyn again. Cindy has no problem with anyone being transgender, but no woman wants to be told that she looks like a man who's had a sex change."

What's more, the site also suggests that Amal's Caitlyn comparison has forced Cindy to consider chopping off her hair and wearing glasses so she doesn't look like the former Kardashian family member anymore.

So far, neither Amal nor Cindy have made any comments about the report. The last time the two women have been spotted together was during a trip to Ibiza with their husbands back in September.
