Sienna Miller, 41, throws a lavish baby shower as she prepares for the birth of her child with boyfriend Oli Green, 26 – and gives MAJOR clues about the gender of their unborn baby

Sienna Miller gave a major hint about the gender of her unborn baby when she hosted an elaborate shower this weekend.

The actress, 41, is expecting her second child, and her first with boyfriend Oli Green, 26.

The notoriously private star has yet to publicly announce her pregnancy, but the news was confirmed when she showed off her baby bump while in a bikini on a beach in Ibiza in August.

She is already mum to Marlowe, 11, who she shares with her ex Tom Sturridge.

But after hosting an extravagant baby shower with friends and family this weekend, fans quickly suspected she was expecting another girl.

The beautiful Sienna showed off her blossoming belly in a baby pink dress, accompanied by a flower crown with different shades of blush, again a reference to a girl.

Additionally, her home was decorated with pink balloons in every shade of the color, while her sister Savannah added a slew of pink hearts and flower emojis to her Instagram caption.

Sienna’s guests were all dressed in shades of pink and white, while the house was carefully decorated with fresh flowers, cloud balloons and even had a nail salon.

Sienna has yet to confirm the gender of her baby.

Savannah wrote, “Last night we showered @siennathing with love in preparation for the most exciting arrival. It was pure magic. I can’t wait to meet the newest member of our family.’

The baby will be Ms. Miller’s first child with Green, who is 15 years her junior.

She first sparked speculation that she was pregnant when she was spotted on a beach in Ibiza in August wearing a swimsuit that showed a bump.

The star later went public at the Vogue World event last month, where she posed on the red carpet in a gown that confirmed she was expecting.

Ms Miller already has a ten-year-old daughter called Marlowe from her former relationship with fellow actor Tom Sturridge.

She and Green first became romantically involved in early 2022 when they were spotted together in New York.

He is also an actor who will play Rupert Finch, a university friend of the Prince and Princess of Wales while they were at St Andrews, in the upcoming series of The Crown.

Anatomy Of A Scandal star Mrs Miller revealed she was planning to freeze her eggs, saying: ‘I would like to have more children.

‘I would love it for my daughter too. I think I would be open to getting married.’

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

She said: ‘I would love to have more children. I would also really like it for my daughter. I think I would be open to getting married.’

The star was in a relationship with Lucas Zwirner at the time, but they eventually broke up the following year.

Sienna previously told how she felt ‘overwhelmed’ and thought she had ‘failed’ the early stages of parenthood after having 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 she had a ‘traumatic birth’ with her daughter and felt like she had ‘failed’ at the time by not being in a ‘blissful little bubble’.

Speaking on This Morning she said: ‘I remember when I had Marlowe, yes, people would call and say, ‘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 lose 24 hours of sleep a week at night, you spend so much time preparing for the birth 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.’

More recently, Sienna spoke about her relationship regrets, saying she previously hoped to get married and have three children by age 30.

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

She said British Vogue: ‘I had invested what felt like important years in something that was nothing more than a person’s bucket with a hole in it. I’ve wasted time. And I felt like time was really my currency.”

For example: Prior to her relationship with Tom, Sienna was engaged to fellow actor Jude Law in 2004 after he popped the question on Christmas Day (pictured in 2010)

Sienna was quick to point out that she wasn’t talking about 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 the following year for having an affair with his children’s nanny.

Looking back on her 30s, she added: “There was a lot of fear. The relationships didn’t work out – I imagined myself being married with 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 said: “There is a misogyny that is 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.
