Sienna Miller confirmed her pregnancy in a unique way by showcasing her baby bump at a Vogue event in London. The 41-year-old actress, who is currently in a relationship with actor Oli Green, wore an outfit that emphasized her protruding stomach. This will be Miller's second child, with her first being a 10-year-old daughter named Marlowe from a previous relationship. The news of her pregnancy emerged last month with photos showing her wearing a bikini with a baby bump. While Miller hinted at the reports, she did not confirm them until her appearance at the Vogue event.
