Sienna Miller is pregnant with her second child!

In photos obtained by People, the actress, 41, can be seen showing off her growing baby bump in a rusted brown-toned bikini while vacationing in Ibiza. She accessorised with red feathered earrings, a gold chain and a navy sarong. Having just been joined by her partner, Oli Green, 26, in St. Tropez, it looks like the Anatomy of a Scandal star is enjoying a babymoon.

While Miller is already a mother to her 11-year-old daughter, Marlowe Ottoline Layng Sturridge, whom she shares with actor Tom Sturridge, this is Green’s first child.

Last year, during an interview with ELLE UK, Miller opened up about the pressure to decide quite quickly whether or not she wanted more kids as she turned 40, describing it as a “really loud noise”.

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