Holly Madison is feeling much better after being hospitalized for extreme morning sickness Dec. 3.

"When it started happening really late [in my pregnancy] and I was really vomiting a lot during the day, it freaked me out," the 33-year-old told Entertainment Tonight Dec. 4. "I was told to go to the doctor and get an IV and everything. So, that was kind of scary to me just because it seemed like something so unusual, something that I hadn't read about. But everything's OK so far, so that's good."

Madison added, "I'm excited to get through these last months of pregnancy. Hopefully no more scares."

This will be the first child for Madison and her boyfriend, Electric Daisy Carnival founder Pasquale Rotella. "I'm almost seven months," the blonde bombshell said. "I'm due the first week of March."

Until their little girl arrives, Madison has been instructed to take things easy. "I was threatened with bed rest," she admitted. "I haven't been given bed rest yet, but they're like, 'You better take it easy and don't lift anything over 5 lbs.'"

Luckily, that gives the couple plenty of time to settle on a baby name. "We actually have a lot of names we really like, so we're narrowing it down and I think we're going to wait until the day the baby comes and see what her vibe is and then pick one from there," Madison explained.

Madison also shared well wishes for Kate Middleton, who is receiving medical care at London's King Edward VII hospital for complications from hyperemesis gravidarum, an acute form of morning sickness.

"I wish her the best and I'm glad she's getting the best possible care and I'm super excited for her," Madison told Entertainment Tonight. "I think everybody wants to see [the baby] named Diana if it's a girl. I think that would melt the hearts of the world."
