Actress Uma Thurman is expecting baby number three, due later this summer.

This will be Thurman's first child with financier boyfriend Arpad Busson. Thurman and ex-husband Ethan Hawke have two children together, daughter Maya, 13, and son Levon,10.

A rep for the 41-year-old actress confirmed pregnancy reports to People magazine. The story was first reported by Life & Style.

A friend of Thurman's told Life & Style that pals could tell something was up when they saw her at New York Fashion Week, where the former model covered up with a baggy blouse and loose blazer.

"She's usually so skinny, but now she has the cutest little bump and a glow about her," the friend said.

Thurman, best known for her roles in Kill Bill and Pulp Fiction, is set to guest star in the NBC musical drama Smash with an upcoming five-episode spot, where she'll play what's been described as a "famous and somewhat difficult movie star."
