Come on, Nick Cannon and Mariah, why don’t you just admit you’re expecting? Why else do you need a book about parenting?

We no longer have to wonder whether 40-year-old singer Mariah Carey really is pregnant because we have proof that she and husband Nick Cannon, 29, are prepping for a baby!

One of Mariah’s friends picked up a copy of Dr. Jenn Berman‘s new parenting book SuperBaby: 12 Ways to Give Your Child a Head Start in the First 3 Years at a book signing Sept. 15 at Little Seed baby boutique in L.A. to give to the singer. And the clincher is that the friend had the book personally signed saying, “Dear Mariah, Congratulations!”

“She went up to the author and said, ‘Please sign this for Mariah — and make sure it says, ‘Congratulations,'” a source told FOX411.com. “Dr. Berman smiled and wrote something like, ‘Dear Mariah, Congratulations! I hope this helps you through the first three years.'”

Wow! We are super excited to hear that Mariah and Nick really are expecting and now Mariah has a great book to guide her through the first three years of parenthood.
