Sienna Miller Glows at Fashion Awards, Reveals Baby Bump

Sienna Miller, 43, has announced she is expecting her third child. The actress revealed the happy news while attending The Fashion Awards 2025 in London, making a memorable appearance alongside her boyfriend, Oli Green. Miller proudly displayed her baby bump in a daring, sheer white Givenchy gown, drawing attention on the red carpet.

This pregnancy marks a new chapter for Miller and Green, who welcomed their first child together, a daughter, in 2024. Miller is also a mother to her 13-year-old daughter, Marlowe, from her previous relationship with Tom Sturridge. Her latest public appearance, just weeks prior, saw her subtly concealing her pregnancy.

Miller previously spoke about the pressures of expanding her family, having frozen her eggs at age 40. She reflected on the biological clock and the "existential threat" diminishing as she embraced a more relaxed approach to having more children, stating "if it happens, it happens."
