Actress Uma Thurman is Pregnant!

Uma Thurman is expecting her first child with long-term partner financier, Arpad 'Arki' Busson, after years of on and off dating.

"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," a source told Life & Style magazine.

The "Kill Bill" actress currently has two children with ex-husband, Ethan Hawke, while Busson also has two children with his ex-fiance, Elle Macpherson.

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

The 41-year-old reportedly began dating Busson in 2007, but they broke it off in 2009 after getting engaged and in 2011 rekindled their romance.

While it is unclear whether the couple has become engaged again, they appear to be serious with friends and family hoping for a wedding following their baby news.

Thurman, also a former model, appears to have taken a break from the big screen in recent months but is reportedly scheduled to star in the hit TV show "Smash," where her singing skills will be put to the test.

"I do some singing, but not very well! I am probably not going to be offered a record deal off of this, but I enjoy it," quoted Thurman as recently saying.

"It is so much fun. I get to do a number. Whenever you start to sing or dance you probably think you don't want to do it and then you start and you can't stop - even if everyone else wants you to!" she added.

Thurman is one of Hollywood's most sought after actresses who has one a number of prestigious awards for her role in Quentin Tarantino's hit films "Pulp Fiction," and "Kill Bill - Vol. 1, 2 and 3."

The expectant mother is also known for her philanthropic work with USAID, an organization which specializes in foreign aid and once participated in a campaign seeking to abolish gun laws to improve national safety.
