In an interview with Elle in 2022, Miller admitted feeling “pressure” to have more children in her 20s and 30s. She also revealed after she turned 40, she decided to freeze her eggs.

The actress explained that she felt “pressure… [about] kids, and should I have more, and why haven’t I, and all of that, which is a really loud noise.”

She continued, “Biology is incredibly cruel on women in that decade — that’s the headline, or it certainly was for me.”

“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,” Miller said.

Oli and Sienna were first spotted out and about together in February 2022, according to E! News. In an interview with British Vogue that same year, Miller explained to her relationship with Green helped change her outlook on relationships and marriage.

“I’d invested what felt like the important years in something that was just a bucket with a hole in it of a person,” she told the outlet. “And I felt like time was really my currency. There was a lot of anxiety. Relationships hadn’t worked out — I imagined that I would be married with three kids, being a great mum.”

“When you are raising a child you see aspects of your character in that person, reflected back, and it’s the most loving, intense relationship that I have,” she said at the time. “There’s nowhere to hide.”

“She knows me, I know her,” Miller continued. “She’s really stubborn, which is very like me. I see her as her own person but I also see genetic things. She’s heaven, my kid.”
