Jim Carrey is a grandpa! So what does that mean for girlfriend Jenny McCarthy?

As of 12:28 a.m. Friday, Jim Carrey is the grandfather of a new baby boy -- his daughter, singer Jane Carrey, delivered Jackson Riley Santana today in Los Angeles. Alex Santana, who's also in a band, is the proud dad of the 7 pound, 11 ounce kiddo.

Jane and Alex got married in November, with Jim walking his daughter down the aisle.

So what does it all mean for girlfriend Jenny McCarthy, who's been with the actor for years? After all, she does have a 7-year-old son of her own.

"I will be called 'grandmother,' with or without a [marriage] certificate," McCarthy, 37, told the Ministry back in December. "That baby is going to be mine!"

She said just last weekend that she might marry Carrey some day: "Maybe for tax purposes, someday, when we are old."

Congrats to all involved -- happy grandparenting.

Well, I guess this might mean no childhood protective vaccinations for the baby. You don't want to cross that anti-vaccinationist "Dr" J. McCarthy....Jane and Alex, please ignore what this dangerous "Grandmother" might tell you. Protect your precious child and listen to your pediatricians.
