Holly Madison reveals she's expecting a son

Holly Madison is expecting a baby boy.

The former Playboy Playmate and her husband Pasquale Rotella revealed back in January (16) that they would be adding to their brood with another addition. They are already parents to three-year-old daughter Rainbow.

The couple, who married in 2013, confirmed they are expecting a boy to People.com via their representatives.

Holly previously revealed that she had a strong feeling she might be having a boy, telling People in January: "I'm kind of feeling the boy vibe. We'll see how psychic I am!"

It remains to be seen what Rainbow thinks of the news she'll be getting a brother, as Holly had said: "She is rooting for a girl."

However, she added: "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."

With her son due to be making his arrival this summer (16), Holly is doing her best to get herself and her house ready. One good thing though is that she is dealing with pregnancy better the second time around.

"I've been really lucky, not a lot of nausea or anything," Holly told Us Weekly in March (16). "I'm not reading up on it every day like I was with (Rainbow), I'm just busy chasing after her so the time is going by super fast. I blinked and half the pregnancy was over."

Holly admitted she is struggling though with tiredness. Hardly surprising considering she's mother to a toddler and has her second book The Vegas Diaries due to hit shelves in May (16).

"I just get tired super easily," she added to E! News last month (Mar16). "Like, yesterday I was catching up with my friends, and I was just telling stories I was excited about and I'm like dead out of breath at the end of it. I was like, this is embarrassing. I feel like I just ran a marathon!"
