The Oscar winning actress expects her first biological child in July. She has 2 adopted children with ex-husband Tom Cruise Connor, 13 and Isabella, 16.

Wearing a yellow summer dress, Kidman’s modest bump was difficult to see, despite being in her final trimester.

I agree, but it is worth mentioning that Nicole is so tall, her bump doesn’t really ‘pop’ out the front like other smaller celebrities.
