'Project Runway," (search) Bravo's runaway hit reality show, will strut again next season.

Network execs are breathing a sigh of relief because the future of the show was in question, thanks to the unraveling relationship between Bob and Harvey Weinstein, the heads of Miramax, the studio behind the series, and parent company Disney.

"We always negotiated with Miramax," Bravo chief Lauren Zalaznick told The Post. "We're thrilled, thrilled to make this happen."

While the ownership of "Runway" is still in question -- no one is sure which properties the Weinsteins or Disney will keep ("that's a question for Miramax," Zalaznick says) -- the series could be back as early as early as next fall.

On the show, a group of designers compete for a big-bucks contract to produce a line of apparel. The show is hosted by supermodel Heidi Klum (search).

Production on the new season will begin right away, Zalaznick says.

"This is such a casting-dependent, creative show that until we see what we have, it doesn't make sense to put a peg on the date board [as to when it will debut]," she says.

Very little on the show will change, Zalaznick says.
