The actress has been datingher 28-year-old boyfriendsince 2022 and has previously opened up about the "pressure" to grow her family after turning 40.
In a 2022 interview withElle UK, she discussed the topic and revealed that she'd had some of her eggs frozen.
"[The] pressure... [about] kids, and should I have more, and why haven't I, and all of that, which is a really loud noise. Biology is incredibly cruel on women in that decade – that's the headline, or it certainly was for me," she shared.
"Then I got to 40 and I froze some eggs. Having been really focused on the need to have another baby, I'm just like, if it happens, it happens. That kind of existential threat has dissipated."
