Carol Burnett may be best known for her work on the hit sketch comedy show, "The Carol Burnett Show," but the 80-year old actress, who celebrates her birthday today, worked hard to get noticed.

When Carol moved to Hollywood in the 1930s, she worked as an usher at a Hollywood theater, and it was at the Hollywood Pacific Theater where she first caught the acting/comedy bug. After graduating from high school, Carol attended UCLA. She quickly realized that this bug was indeed a passion for theater arts and turned her focus towards a budding playwright career.

Carol got her first big break in 1959 when she was cast in the musical "Once Upon a Mattress," for which she was nominated for her first Tony Award. When CBS approached Carol in 1967 to host a variety series called "The Carol Burnett Show," her career changed forever. The show lasted more then 10-years and continues to run on syndication television today.

On TV, Carol's style adapted to the roles she played. Whether she was dressed as the cleaning lady in one sketch or a teacher in another, her ability to transform into a character was further amplified by the costumes. In her personal life, Carol's style was classic. We've seen her in chic sleeveless dresses, embroidered tops, and over-the-top blazers. Her style truly transformed with each decade of her success.

Today, Carol's style is simple. She continues to wear fitted blazers and chic skirts, but gone are the days of shoulder pads and sequins. She regularly appears on television and speaks in front of sold out audiences. She was even honored with the Presidential Medal of Freedom by President George W. Bush in 2005.
