Holly Madison is pregnant.

The reality TV star - who previously dated Playboy mogul Hugh Hefner - and her party promoter boyfriend Pasquale Rotella will welcome their first child into the world early next year and the pair couldn't be happier.

However, the blonde beauty admits the news was a bit of a shock as she expected to take a while to get pregnant.

Holly - who is 12 weeks pregnant - told Us Weekly magazine: ''I've always wanted to be a mom. But I thought it would take longer!''

The 32-year-old beauty is experiencing some sickness and is trying to take precautions to ensure her nausea doesn't affect her role in Las Vegas burlesque production 'Peepshow'.

She added: ''I've been lucky! No morning sickness, but I do get a little nauseous. It happens before my show, so I keep ginger ale backstage.''

In June, Holly declined against renewing her contract for 'Peepshow' and admitted at the time she was keen to start a family with Pasquale, who she has been dating for nine months.

She said: ''I've wanted kids and that's something I'm definitely doing as soon as possible.

''Definitely being with the right guy has a lot to do with it. My relationship is awesome. I'm happier than I've ever been in my personal life.''
