Oh boy, Hollywood couples are nesting like crazy these days.

I hope Petit Tresor - the exclusive baby boutique to the stars on Robertson Blvd - is stocking up on designer furniture and accessories to meet the upcoming demand!

I mean, gosh, we don’t want these celebrity parents-to-be forced to shop at (gulp) Wal-Mart, do we?

Here’s the current list (more seem to get added to it by the week):

• Matthew McConaughey and Brazilian model girldriend, Camila Alves, are expecting.
• Nicole Kidman and Keith Urban - ditto.
• Jack Black and wife Tanya Haden - preggers and about to deliver.
• Singer Robin Thicke and wife Paula Patton have yet to confirm publicly their expectancy.
• Jamie Lynn Spears is pregnant with her very own Cabbage Patch Doll.
• Jessica Alba and boyfriend Cash Warren expecting.
• Angela Kinsey of “The Office” is due in the spring.
• Chris Noth and girlfriend Tara Wilson are reportedly five months along.
• Elisabeth Rohm of “Law and Order” fame is giving birth in April.
• JLo - we already know about her package yet to be delivered.
• Cate Blanchett and her husband have another bun in the oven.
• Jodie Sweetin from “Full House” has a baby bump of her own.
• Halle Berry and her model boyfriend - ditto.
• Actress Toni Collette is preggers.
• Jacinda Barrett takes up the rear with her own little bundle of joy on the way.

A baby boom in Hollywood is definitely underway. Who will be next? Who won’t be next? All we can do is wait and see where the baby bump strikes…again!
