Debra Wilson

Biography: A broad comic actress known for her outrageous impressions of Oprah Winfrey and Whitney Houston on the sketch comedy series Mad TV, the prolific Wilson has also tackled a plethora of supporting roles on the big and small screens. Mad TV's longest-running original cast member when she finally left after eight seasons in 2003, the dreadlocked funny woman continued to pop up as kooky characters in a variety of projects. But she was particularly hilarious as a commentator on various E! specials, which helped her land a gig as cohost of TV Guide Channel's sassy entertainment series TV Watercooler in 2006.
