Her impending arrival will be her first with boyfriend, financier Arpad Busson. She is already mum to Maya, 13, and Levon, 10, her children from her relationship with Ethan Hawke, while Arpad also has two children, Arpad Flynn Alexandra and Aurelius Cy Andrea, with former girlfriend and presenter of Britain and Ireland's Next Top Model, Elle Macpherson.
A spokesperson for the Kill Bill star confirmed the news after rumours about her baby bump started circulating across the pond. Before the official announcement, a "friend" told Life & Style magazine: "She's excited. She's happy and just a few months along right now. She's due in late, late summer.
"A lot of her friends were asking her because they could tell the difference when they saw her at New York Fashion Week. She's usually so skinny, but now she has the cutest little bump and a glow about her".
Congratulations Uma and Arpad!
