News of Sienna’s pregnancy comes after she previously revealed she had frozen some of her eggs after she turned 40.

Speak against ElleSienna shared how she often wondered, “Should I have more (children), and why didn’t I, and all that, which is a very loud noise.”

“Biology is incredibly cruel to women in that decade — that’s the headline, and at least it was for me.”

She added, “Then I got to 40 and froze some eggs. Because I’m really focused on the need to have another baby, I think if it happens, it happens. That kind of existential threat is gone.”

In 2019, Sienna told The Sunday Times Style Magazine how she hoped to grow her family in the future.

She said, “I would love to have more children. I would also love it for my daughter. I think I would be open to getting married.”

The star was dating Lucas Zwirner at the time, but they eventually broke up the following year.

Sienna previously shared how she felt “overwhelmed” and thought she had “failed” the early stages of parenthood after welcoming Marlowe in 2012.

Reflecting on the difficult time, the actress said she was “obsessed” with Marlowe, but at the same time was also in “absolute hell” because she “didn’t know what she was doing.”

Sienna revealed that she had a “traumatic delivery” with her daughter and felt she had “failed” at the time by not being in a “blissful little bubble.”

Speaking on This Morning, she said, “I remember when I got Marlowe, yes, people called and said, ‘I’m sure you’re in your blissful little bubble’ and I was obsessed with my daughter, but I was also in absolute hell.

“Because you’re losing 24 hours of sleep a week at night, you spend so much time preparing for labor and then you have to take the baby home and I didn’t know what I was doing.

“It was intense, I had a traumatic birth, but I felt like I had failed at something by not being happy in the early stages of parenthood.”

The actress wanted a “natural water birth,” but instead endured a painful 27-hour labor that ended in an emergency caesarean section.

More recently, Sienna spoke candidly about the regrets of her relationship, saying that she rather hoped to get married by the age of 30 and have three children.

The actress said she spent years investing in a relationship with someone who was “a bucket with a hole in it of a person.”

She said British VogueI had invested what felt like significant years into something that was no more than a person’s bucket with a hole in it. I wasted time. And I felt like time was really my currency.”

Sienna was quick to point out that she was not referring to daughter Marlowe’s father, Tom Sturridge, who she dated from 2011 to 2015.

Prior to her relationship with Tom, Sienna was engaged to fellow actor Jude Law in 2004 after he popped the question on Christmas Day.

He apologized to her in July of the following year for having an affair with his children’s nanny.

Sienna also had a highly publicized affair with actor Bathlazar Getty in 2008.

Reflecting on how her thirties were tough, she added, “There was a lot of anxiety. The relationships hadn’t worked out – I imagined being married and having three kids, and being a great mother. I love being a mother. That’s what I’m best at.’

Discussing her relationship with Oli, who is 15 years her junior, Sienna added, “There’s a misogyny that’s deeply ingrained in men my age and older that I don’t see in (the) generation below.”

Sienna’s ex Tom is now in a relationship with presenter and fashion designer Alexa Chung, with the actress saying she is “very happy” for the couple.
