Apparently Heidi Klum was right all along.  A month after Klum first announced it and Bravo denied it, the network has formally confirmed that Project Runway's fourth season will premiere on Wednesday, November 14 at 10PM ET/PT and revealed the identities of the season's 15 contestants.

Production on Project Runway 4 began earlier this year when Bravo announced the Emmy-nominated reality competition series would not air as part of its Summer 2007 programming schedule and was instead scheduled to premiere in late 2007. 

"Watch the new season of Project Runway beginning Wednesday, November 14th, only on Bravo (check your local listings)," Klum posted on her personal website last month.  "I consider it to be our best season yet!"

However when contacted to confirm Klum's announcement, a Bravo spokesperson told Reality TV World the network still planned to debut Project Runway 4 in the "fourth quarter" and added an exact premiere date had not yet been determined.

"Maybe [Klum] knows more than us, but I don't think so," the spokesperson told Reality TV World.

Project Runway 4 isn't the first time that Bravo has guardedly handled a Project Runway edition premiere date.

Last year, a Project Runway 2 DVD advertisement published in the April 2007 issue of Video Business teased that the second season's DVD release would come "just in time for the TV premiere of Season 3, airing July 12 on Bravo."   However despite the ad, a Bravo spokesperson reached by Reality TV World at the time would still only confirm that Project Runway 3 would definitely air in the summer.  Six weeks later, Bravo officially announced July 12 as Project Runway 3's premiere date.

Like its first three editions, Project Runway's fourth season will once again be hosted by Klum and feature clothing designer Michael Kors and Elle Magazine fashion director Nina Garcia as part of the show's judging panel.  Fashion guru Tim Gunn will also return to help mentor and guide the contestants through the competition.

"It is very exciting to be going into our fourth season of Project Runway, and I think it will be the best season yet -- I'm sure the audience will enjoy it," Klum stated in today's announcement. "Fashion is such a difficult business, and besides being great TV, we're proud that the show allows some very talented designers to have a platform."

Project Runway 4's winner will receive a $100,000 TRESemme-sponsored cash prize intended to help launch their own clothing line, a 2008 Saturn Astra, an ELLE magazine editorial feature, and the opportunity to sell a fashion line on (unlike Project Runway's first three seasons, the fourth-season prize package will apparently not include a design "mentorship" from a sponsor like the Banana Republic or Macy's).

The 15 contestants competing on Project Runway 4 are:

- Carmen Webber, a 37-year-old from Charlotte, NC

- Chris March, a 44-year-old from San Francisco, CA

- Christina "Kit" Scarbo, a 26-year-old from Los Angeles, CA
