Let's make this birthday one to remember.

60 years old (Born on July 03, 1964)

Voice actor; She is famous from Voice of Lisa on The Simpsons.

Her father, J.Y. Smith, who died in 2006, was a longtime obituary writer for The Washington Post. Originally read for the role of Bart when auditioning for "The Simpsons" (1989), but her voice was too high and sounded like a girl, so she lightened her voice up a little and auditioned and won the role of Lisa. Ironically, Nancy Cartwright originally read for Lisa, but was given the role of Bart. Of the core 6 Simpsons performers, Yeardley is the youngest. Her name is pronounced "Yard-lee". Is only one of two actresses (the other being Marcia Wallace) on "The Simpsons" (1989) to regularly play only one character. All of the other actors play ten or more characters.
