Uma’s new bundle of joy was definitely not part of a plan,according to a source. “It was a surprise. But she’s over the moon about it,very excited.”

The star began dating Arpad back in 2007 and briefly splitin 2009. They quickly got back together and have been a couple ever since. Onething missing from all this: the baby’s name! We’ll be waiting patiently untilthat gets released. Kinda of an important part, don’t you think?

Congrats to the happy couple!
