The 8 Most Famous Singer-Actors in Entertainment

3. Christina Applegate

The 43-year-old actress has come a long way since her days as Kelly Bundy in Married…with Children. With a knack for comedy, Christina Applegate starred in over a dozen flicks, including the Anchorman series and The Sweetest Thing. However, she also demonstrated that her voice is a force to be reckoned with, lending her pipes to numerous Broadway musicals, such as Sweet Charity. Not to mention, she did all this and also fought off breast cancer. A round of applause for this brave double-threat.
