WWW- OH, baby! Scads of celebrities are in the mood to infanticipate in 2006, while many others are poised to tie the knot.

* Naomi Watts [pictured] is desperate to get pregnant. The "King Kong" cutie, 37, and boyfriend Liev Schreiber are said to be hard at work trying to get Watts in a motherly way while on vacation in Australia.

* Believe it or not, Britney Spears wants another baby with shiftless hubby Kevin Federline. Spears is set on a daughter to go with her son, Sean Preston. According to InTouch Weekly, she thinks a second child will bring her and Federline "closer."

* Sheryl Crow is hoping to get impregnated by fiancé Lance Armstrong. The singer has checked out fertility treatment centers, sources tell PAGE SIX, as potential daddy Armstrong had testicular cancer and froze his sperm.

* The bump watch is also on for Angelina Jolie. Us Weekly printed a series of photos of the sexy star wearing loose-fitting clothing and looking as if she'd gained weight. Supposed daddy-to-be Brad Pitt is already in the midst of trying to become the official father to Jolie's adopted children, Maddox and Zahara.

* Another rumor in Hollywood is that Tori Spelling got engaged to her new man, Dean McDermott, so fast because she's with child. Spelling isn't even divorced from her hubby of one year, Charlie Shanian, yet. We don't know for sure because her rep, Cece York, didn't return our calls.

* Jennifer Aniston, Pitt's ex, is also said to yearn for children. The actress, who has claimed in interviews that she wants kids soon, is currently holed up at the Montage Hotel and Spa in Laguna Beach with boyfriend Vince Vaughn, our spies say.

* A nuptials watch is also on for Crow and Armstrong, Pitt and Jolie, and Nicole Kidman and her country crooner, Keith Urban - all of whom are said to want to tie the knot soon.

* Meanwhile, Kate Bosworth and Orlando Bloom are expected to announce their engagement any day now, and Howard Stern has vowed to make a "huge" announcement on Jan. 9, his first day at Sirius radio, which could be the news of a rumored wedding to Beth Ostrosky.

Ah, love!
