NBC says it is planning to air a 2-hour edition of its Costa-Rican-set competition series "I'm a Celebrity Get Me Out of Here!" next week.

The Wednesday telecast is in addition to the previously announced 2-hour installment set for Monday.

Tuesday, the network will carry Game 6 of the Stanley Cup finals between the Detroit Red Wings and the Pittsburgh Penguins.

"Next week's exciting episodes will showcase Heidi and Spencer's nightmarish adventure inside the creature-infested 'Lost Chamber' and the fate of their return," NBC said in a news release. "Meanwhile, the hazardous conditions of living in the jungle come to the forefront and begin to take their toll on our celebrities."

Married contestants Heidi Montag and Spencer Pratt quit the show this week, but have since been campaigning to get back on the series.

After next week, "Celebrity" will air Mondays-Thursdays in its regular 8 p.m. to 9 p.m. time slot until the final week of the show, with the finale to take place Wednesday, June 24, NBC said.

Also competing on the show are Janice Dickinson, Patti Blagojevich, wife of the former Illinois governor, Lou Diamond Phillips, Sanjaya Malakar, John Salley, Stephen Baldwin, Torrie Wilson and Frances Callier.
