Holly Madison’s second pregnancy is much tougher.
The former Playboy model – who already has Rainbow Aurora, three, with her husband Pasquale Rotella – admits she is feeling much "slower and more tired" during her second pregnancy.
She said: "Rainbow is very excited to be getting a little brother! I fit my book tour in at the last minute. I have two more months to go, and I feel very slow and tired. This pregnancy is a lot harder than the first one!
"I think staying onstage for the first five months of my last pregnancy really set the tone for my physical fitness. This time around, I was sitting at my computer in edits for the first five months."
And the 36-year-old ‘Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny’ author says she is "definitely happier" now because she has found a balance between her career and her personal life.
She added: "I am definitely happier than ever now because I feel like I have a balance between a professional life and a personal life. I finally give myself a weekend now so I can spend uninterrupted time with my family.
"I had fun back in my workaholic days, too, though, and I am really glad I had that time in my life when I was single in Las Vegas, just working on me and my career, because it’s important to have a solid sense of who you are before settling down."
Meanwhile, Holly hasn’t ruled out the possibility of having more children one day.
She told the Las Vegas Sun newspaper: "My husband and I would love more kids, but we are going to take it slow, too. I loved having 3 1/2 years to get to know Rainbow before adding another one to the mix."
