Richard Keith – 70 years old

Net worth: $1 Million

Professionally known as Richard Keith, Keith Thibodeaux is a former child actor and musician whose most notable role is Little Ricky on the TV sitcoms I Love Lucy and The Lucy-Desi Comedy Hour. Considering that his last name is too difficult to pronounce, producer Desi Arnaz gave him his popular screen name that we all know and love today. At age 70, Keith is the only living regular cast member in the aforementioned sitcom. Other screen projects he was in include The Lucy Show and The Andy Griffith Show. Interestingly, during the late ‘60s, he joined a band named David and the Giants.

Keith had problems with illegal substances. Adding gas to the fire is him leaving the band. These adversities he experienced made him decide to convert from a Roman Catholic to becoming a born-again Christian, which was a way for him to turn a new leaf.
