THE real world has put a damper on MTV’s “The Real World.”

A dispute between labor unions and the producers of the long-running reality hit has put the kibosh on the show’s 15th season, which was about to be filmed in Philadelphia.

Bunim-Murry, the show’s producer, had angered labor unions by hiring a non-union company to renovate a Philly church in the part of town called Old City, according to the Philadelphia Inquirer.

The producers had planned to house the show’s cast members in the renovated church.

A spokeswoman for “The Real World” did not return calls yesterday.
