Initially famous for her Logie Award-winning portrayal of Hayley Smith Lawson on the popular Australian soap opera Home and Away, she went on to record a hit Australian pop music album that she released under her maiden name of Bec Cartwright.
She appeared in her first television commercial when she was five years old and was cast in her first television guest spot -- on the series Police Rescue -- when she was nine.
She competed in and won the first season of the Australian version of Dancing with the Stars.
Born Rebecca June Cartwright, she spent her youth in Sydney, Australia. In 2005, she married champion tennis player Lleyton Hewitt; the couple subsequently welcomed children named Mia, Cruz, and Ava.
Hewitt's friend and Home and Away castmate Ada Nicomedou served as a bridesmaid at her wedding.
