She should really keep her opinion to herself.

Jenna Jameson caused quite the controversy by hopping on Twitter and criticizing Playboy for featuring transgender model Ines Rau in their latest issue, but she's not backing down from her stance.

"So @playboy just announced it will be featuring its first transgender playmate. I have a problem with it just like I have a problem with a transgender competing against biological women in sports. And women and men are two different things. see what I did there?" she wrote in a series of tweets.

"Just because I don't agree with a trans person being in Playboy doesn't mean I'm "transphobic." People these days with all their "phobics.' Because I think it's setting fire to an iconic brand and pandering to this ridiculous PC world we live in 👍🏻," she continued.

"Just because Miss USA won't let me compete (because I'm an ex pornstar) doesn't mean they don't love me 👌🏻I love my gay and trans peeps. I am certainly not back pedaling... I don't think trans belong in Playboy. Period," she added.

Ugh. She's the worst.
