Inside Alyssa Milano's Baseball-Themed Baby Shower

Alyssa Milano's baby boy better love baseball!

The 38-year-old mom-to-be is a huge fan of the L.A. Dodgers -- so much so, that her baby shower took place at Dodger Stadium on Sunday.

Milano and her talent agent hubby David Bugliari celebrated their baby-to-be with 35 of their closest friends, a source tells Us Weekly. Guests included Holly Robinson Peete, Colin Hanks and Twitter founder Jack Dorsey.

The fete included Dodgers cupcakes from Crumbs Bakery. The Who's the Boss star posted a photo of herself on her blog holding up a tiny, custom-made Dodgers jersey.

She thanked her guests on Twitter "for making this day so special. We made memories and I'm so grateful."
