Kate Hudson Baby Boom

Kate Hudson has become the latest to join the Hollywood baby boom sweepstakes. Hudson and musician boyfriend, Matthew Bellamy are expecting, according to several sources, although the pregnancy wasn’t exactly planned.

The actress, 31, joins Natalie Portman; celebrity stylist Rachel Zoe, who is seven months along; singer Jewel and husband Ty Murray; Owen Wilson and Jade Duelle; Oscar-winning actress Marion Cotillard and David and Victoria Beckham.

Wait, there’s more.

Supermodel Miranda Kerr and husband Orlando Bloom welcomed a boy into the world Thursday (Jan. 6). And, John Travolta and wife Kelly recently had a baby boy.

David Schwimmer, who recently got married, is also about to become a father with wife Zoe Buckman.

Hudson was somewhat of a surprise addition. She said the baby wasn’t exactly planned, but is welcomed nonetheless.

“They couldn’t be more excited,” a source tells People. “Kate is really happy. She was always excited to have kids again at some point.”

Hudson has a son, Ryder, 7, with ex-husband Chris Robinson.

She started dating Bellamy, 32, frontman for the rock band Muse, nine months ago on the rebound from a relationship with Yankee slugger Alex Rodriguez.
