Uma Thurman is said to be "excited" about expecting her third child, according to reports.

The baby would be the first with her businessman boyfriend Arpad Busson and she already has two children with ex-husband Ethan Hawke; Maya, 13 and Levon, 10.

A source close to the actress told Life & Style that the 41-year-old is delighted to be adding to her family.

"Yes, Uma is pregnant!" the pal told the magazine. "She hasn't announced it yet, but 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."

The former model was in the front row of the Tommy Hilfiger runway show on February 12 and was unusually covered up in a baggy shirt and a loose fitting jacket.

"She's excited," the source added. "She's happy and just a few months along right now. She's due in late, late summer."

Uma started dating Arpad in 2007 but they split in late 2009. However, they rekindled their romance last year and have maintained their relationship since then.
