The 41-year-old actress - who has 13-year-old daughter Maya and 10-year-old son Levon, with ex-husband Ethan Hawke - is expecting her first kid with her businessman boyfriend Arpad Busson.

A friend of Uma`s told Life & Style magazine: "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."

The couple - who reunited last year following a split in November 2009 - are said to be "excited" about the news, with the baby thought to be due in late summer 2012.

The insider added: "She`s excited. She`s happy and just a few months along right now. She`s due in late, late summer."

Earlier this year, the blonde beauty - who was also previously married to actor Gary Oldman - revealed she is happier in her love life more than she has been in "many, many years".

She explained: "I have something I would really like to express about my love life. I`m happier with it now than I`ve been in many, many years. Yes I`m trying to have as peaceful a personal life as possible."
