The actor and singer told Vanity Fair her chronic health issues, which include a lupus diagnosis, make it risky for her to carry a baby to term and give birth.

The 32-year-old was discussing her role in the film Emilia Perez, in which she plays a young mother, and was also asked about her relationship with songwriter Benny Blanco, who said earlier this year he wants to have children in the future.

"I haven't ever said this, but I unfortunately can't carry my own children," she told Vanity Fair.

"I have a lot of medical issues that would put my life and the baby's in jeopardy. That was something I had to grieve for a while."

Discussing becoming a parent one day, she said: "It's not necessarily the way I envisioned it.

"I thought it would happen the way it happens for everyone. [But] I'm in a much better place with that.

"I find it a blessing that there are wonderful people willing to do surrogacy or adoption, which are both huge possibilities for me.

"It made me really thankful for the other outlets for people who are dying to be moms. I'm one of those people."

Speaking about the next chapter of her life, she said: "I'm excited for what that journey will look like, but it'll look a little different.

"At the end of the day, I don't care. It'll be mine. It'll be my baby."

Lupus is an incurable immune system illness which is believed to be genetic in origin.

The immune system turns against the body and produces too many antibodies, which damage organs and tissues - often irreversibly, meaning many lupus sufferers have transplants.

Gomez herself underwent a kidney transplant in 2007.

While people with lupus can have successful pregnancies, it increases the risks of complications, including kidney problems, blood clots and high blood pressure.
