Rainbow Aurora is getting a brother or sister!

Holly Madison, mom to 2½-year-old daughter Rainbow, is three months pregnant with her second child, she confirms to PEOPLE exclusively.

“I’m so excited,” says the author of Down the Rabbit Hole, 36. “This time I know what to expect a little bit more. [That] makes it even more enjoyable!”

The former Girls Next Door star, married to Pasquale Rotella, doesn’t yet know the sex of her baby on the way, but says, “I’m kind of feeling the boy vibe. We’ll see how psychic I am!”

And big sister Rainbow is getting in on the excitement. “She was the first person my husband and I told,” says Madison, who is due in August.

“She’s rooting for a girl. I think she’s going to be a good big sister. She’s very caring and she loves playing with her baby dolls and taking care of the pets.”

And Madison isn’t feeling any trepidation about her body changing with pregnancy. “I gained a healthy amount last time,” she says. “And I lost it pretty easily. I’m not really putting the pressure on myself. Worst case scenario, I’ll just get lipo!”

As for a name for the new addition, Madison will likely go the unique route once again. “I don’t really like normal names,” she explains. “We have a few finalists.”

But she’s not sharing — yet. Says Madison with a laugh: “I got so much heat for the baby name, I want to wait to share!”

Her daughter has a huge head!

She made some huge errors in judgement when she was younger. I’m glad she has turned her like around and is happy.

All toddlers have huge heads! So rude. Rainbow has an…interesting name, and I probably wouldn’t want her parents as my own, money aside, but she is super cute and I bet she’s a very happy kid.

My 7-year-old daughter’s name is Sunshine. It’s unique and HAPPY! It puts a smile on stranger’s faces when they learn her REAL name is Sunshine and that it’s not just a nickname.

I think her daughter is beautiful with those big gorgeous eyes of hers, and I’m so happy for Holly since finding true love and having a family. Your loss Hef. Oh well, congratulations Holly and husband.

She will probably name this one Rain after Rainbow

Her book acting like Hugh took advantage of her was hilarious. Her own father said in an interview that Hugh actually saved her because she was going down an even more provocative and darker road. Can’t stand people who turn around and spit on the very things that made that got them where they are…

That aside, she did create a very pretty nursery for Rainbow (excited for the next) and I know non celeb people who choose uncommon names for their children. It is not the end of the world like some snooty judgemental people make it seem. People have and will continue to thrive with whatever name they have if they work hard for it. Actions and personality get people places- not their given name. Get over it. Not everyone wants to be an Olivia, Isabella, Noah, or Jaiden and we all aren’t meant to be.

I hope she has a boy as I’m curious for her name style for a male. Either way, hope she has a healthy pregnancy, birth, and child.

Sounder sounds a nice name.

The next name should be Unicorn LOL!

My vote is Spectrum Borealis.

They could always call her “Bowie” for short. I think that would be cute 🙂
