'Project Runway All Stars' Host Alyssa Milano Teases The New Season Including A 'Wicked' Challenge

Project Runway All Stars returns for its fourth season tonight on Lifetime and Alyssa Milano is back to host. The Charmed alum is teasing this season's challenges including a Wicked-inspired round.

The Mistresses star revealed that this season is full of the most talented designers they've had on the All Stars series. "I think we have the most talented group of designers that any season of Project Runway has ever had. It was so hard to judge. With this season of All Stars, it's literally like you're picking the least best. Because these designers turned it out every week, made our jobs so difficult. It's a competitive season-way more than last year," Alyssa told Entertainment Weekly.

One of the coolest challenges to look forward to is the Wicked challenge according to Alyssa. "Yes, I came down in a bubble, eight months pregnant, in heels. We had exclusive access to Wicked, and it's a couture challenge. It was probably one of the most special challenges that I've been a part of," she explained to the publication.

According to a press release from the network via Zap2It, there will be a lot of great celebrity guest judges this season. The guests include, Will & Grace alum Debra Messing, Modern Family star Ariel Winter, singer Nicole Scherzinger, TV host Cat Deely and more.

Alyssa revealed that this season she gets really into the competition, saying her pregnancy during the season's filming had something to do with it. "It was great, actually. I had the best time because we didn't have to hide it. On Mistresses, I was hiding my pregnancy the entire first six months," she told EW.

"It got to be kind of a bummer because you just want to celebrate your body, but instead every single week when you get bigger, bigger, bigger, it becomes more about how hard it is to cover it up. And that just never feels good. But when we were doing Project Runway, it was really just about celebrating it."

The 41-year-old star gave birth to her second child with husband David Bugliari on Sept. 4. They welcomed a baby girl named Elizabella Dylan, who joins big brother Milo, who is three-years-old.
