Designing A Dress For Supermodel Miranda Kerr On 'Project Runway: All Stars' (VIDEO)

It was an exciting fourth week for the remaining designers on "Project Runway: All Stars" (Thu., 9 p.m. EST on Lifetime). Not only did they have the renowned fashion legend Diane Von Furstenburg on the judging panel, but they were designing a dress for supermodel Miranda Kerr. She was on hand as well to pick out the dress she'd most like to wear.

Michael was a huge fan of both Von Furstenburg and Kerr, as evidenced by the O-face he made toward each of them as the judging progressed. With only six hours to work this week -- a new show record for speed -- some of the designers still brought forth stellar work. Mondo received high praise for his cantaloupe-inspired dress for both resembling the fruit and having nice design aesthetics as well.

But it was Michael who had to keep dropping his jaw with his flowing design. "I think it's very fluid," Von Furstenburg. "Yeah, Michael, you gotta call me after the show."

He dropped his jaw again when he was declared the winner of the challenge. Kerr said she felt she could wear the design to many different places and events, so Michael boldly invited her to Palm Springs to wear it while hanging out with him.

While it was good news for Michael, the news wasn't so good for April, who wound up with a very awkward dress. For failing to flatter her model, April was eliminated, but she remained optimistic while leaving. At only 22-years old, she simply takes the show as great experience to learn from as she continues to grow.

"Project Runway: All Stars" continues on Thursdays at 9 p.m. EST on Lifetime.
