Reality shows return

Three networks have announced new seasons of three reality shows.

NBC picked up the weight-loss reality competition The Biggest Loser for a fourth season. Loser has averaged 7.4 million viewers in its third season, down from the 9-million-plus average the show earned last season.

NBC Universal-owned cable channel Bravo ordered up another round of Kathy Griffin: My Life on the D-List. The third six-episode season will air next year, continuing the everyday adventures of the saucy comedienne as she irks Hollywood with her brand of snark-asm.

The CW gave a green light to a third season of Beauty and The Geek, the reality show pairing nerdy guys with hot chicks in their attempts to win $250,000. The show will premiere January 3 at 8 p.m. with a special two-hour episode.
