BURBANK, Calif., June 16 (UPI) -- Christopher Knight will be seen lighting himself on fire for his second week act on the new U.S. competition series "Celebrity Circus," NBC said.

Knight is best known for playing Peter Brady on the iconic 1970s sit-com "The Brady Bunch." He has also starred in the reality shows "The Surreal Life" and "My Fair Brady."

NBC said Knight will perform an "act of fire clowning" on Wednesday's edition of "Celebrity Circus."

Also slated to compete during the six-week series are model Rachel Hunter, actors Antonio Sabato Jr. and Stacey Dash, professional skateboarder Jason "Wee Man" Acuna, R&B singer Blu Cantrell and Olympic gold-medal swimmer Janet Evans.

The June 11 premiere episode of the show was watched by 6.5 million viewers overall and scored NBC's highest non-sports rating on any night of the week for the month of June to date in the adults 18-49 category, the network said.
