The blonde beauty looked every inch the glowing mom-to-be on the red carpet, wearing an ethereal sheer gown from the Givenchy spring/summer 2026 collection.
The Private Life Of A Modern Woman actress wore her blonde locks in boho-inspired mermaid waves, which complemented the netted dress perfectly, and accessorized with furry pink Givenchy heels (we're obsessed!) and statement earrings.
This is her second child with 28-year-old boyfriend Oli Green, and her third overall. She shares daughter Marlowe, who was born in 2012, with ex Tom Sturridge, while she and Oli welcomed a daughter, whose name has not been revealed to the public, in late 2023.
