Where there's Ibiza, there's celebrities. Sienna Miller became the latest A-lister to lap up the sunshine in the White Isle after the actress, 41, revealed she is expecting her second child and first baby with boyfriend Oli Green, 26.

After debuting her baby bump in a bikini on the beach of Spain's most famous party island, the American-British actress attended a glamorous lunch event hosted by royal-favourite fashion label, Self-Portrait. 

The pregnant star looked radiant in a strappy boho maxi dress, reminiscent of her iconic Glastonbury wardrobe that made her the boho style muse of the noughties

Posing against the idyllic backdrop of Cala Gracioneta restaurant, the soon to be mother-of-two was beaming as she posed for photographs with Self-Portrait founder Han Chong. 

Disguising her blossoming baby bump, Sienna's broderie anglaise dress was teamed with a statement metallic belt. The American Woman actress styled her beachy gown with dramatic red drop earrings and a Self-Portrait fan. 

Her blonde hair fell to her shoulders in mermaid-like waves as she rocked a natural golden glow and an immaculate French-tip manicure.

She's known for her roles on the big screen and being a fashion trendsetter, but Sienna Miller's love life has also made headlines over the years.

Sienna and Jude Law become a celebrity power couple when they began dating. They got engaged in 2004 but later split after Jude admitted to having an affair.

In 2008, Sienna was linked to actor Balthazar Getty after being pictured walking arm-in-arm on holiday – but it wasn't to last.

The Layer Cake actress then began dating actor Tom Sturridge in 2011. In 2012, they welcomed their daughter Marlowe. They split in 2015 but remain on great terms as friends and co-parents.

In 2020, it was reported that Sienna and Lucas Zwirner were engaged after two years of dating, but later that year the wedding was called off.

Sienna is now happy with her partner Oli Green. The couple, who began dating in early 2022, are clearly more loved up than ever and are now set to become parents!  

Speaking with Elle UK, she explained she felt "pressure" about kids, and thought: "Should I have more, and why haven't I, and all of that," adding: "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."

Sienna concluded: "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."
