Jenny McCarthy can’t wait to be a grandma after beau Jim Carrey’s daughter, Jane, gives birth in the next three weeks.

“I’m really excited,” McCarthy — who will host the 4th annual Saturday Night Spectacular in Miami this weekend — tells UsMagazine.com. “I think I’m gonna rock as a grandma.”

She says that Jane, who is Carrey’s daughter with his ex wife Melissa Womer, has been calling her for advice.

“She called me up saying, ‘Can I take Tylenol?’ We have an awesome relationship. I consider her my daughter,” McCarthy, 37, tells Us.

But McCarthy, who is mom to 7-year-old son, Evan, with her ex-husband John Asher, tells Us she’ll soon butt out of Jane’s life.

“Mother-in-laws can get annoying once you have a baby because they’re trying to tell you how to raise your baby, and I don’t like anyone telling me how to raise my baby,” she admits. “So I have to learn how to just stay out of it and keep my mouth shut and only give advice when needed. I think that’s what makes a cool grandma – to shut up!”

Just because she’ll soon be a grandma doesn’t mean her relationship with Carrey, 48, whom she’s been dating since 2005, is getting old.

“It’s just night and day comparison to my past relationships. I don’t think I’ve ever liked having sex with someone more than 2 years! It gets boring,” she says. “And you know it’s true love when you still get butterflies with you kiss him. I think just him being my soul mate is the key to everything.
