Uma Thurman pregnant with third child

Break out the cigars for Uma Thurman -- the actress confirmed to People that she's expecting her third child late this summer.

Thurman and longtime boyfriend Arpad Busson began dating in 2007 and aside from a short split in 2009, have been going strong ever since, People reports.

Busson is a financier who has two sons, Flynn, 14, and Cy, 9, with his ex-fiancee Elle MacPherson. Thurman has two kids of her own, Maya, 13, and Levon, 10, with ex-husband Ethan Hawke.

A source tells Life & Style, "Yes, Uma is pregnant! 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."
