Deidre Hall through the years: The 'Days of Our Lives' star is still so beautiful at 71

Like fine wine!

Deidre Hall has graced our TV screens as Dr. Marlena Evans for more than 40 years -- yep, you read that right! She first joined "Days of Our Lives" in 1976, after making the scary jump from one daytime soap for another. She was a series regular on "The Young and the Restless" before finding her permanent TV home.

You wouldn't know it by looking at her, but the actress is now 71 years old. Truly the epitome of "aging gracefully," Hall looked especially lovely in May 2016, when she received a much-deserved star on the Hollywood Walk of Fame.

Outside of "Days," Deidre has starred in a number of programs, including two recent Hallmark Channel movies.

Of course, devoted fans are also familiar with Deidre's lovely twin sister, Andrea Hall. Andrea first appeared on "Days of Our Lives" in 1977, playing Marlena's twin. Two decades later, she would return to play not a blood relative, but simply a Marlena lookalike, Hattie Adams.
