Ashlee Simpson and Evan Ross released their debut single together on Friday (Sept. 7), the romantic duet "I Do." The couple's new song comes ahead of their upcoming E! reality series, Ashlee and Evan, which premieres on Sunday (Sept. 9).
The 33-year-old "Pieces of Me" singer and mother of two hasn't released new music since 2012's "Bat for a Heart," but the collaboration with her multitalented husband -- son of pop icon Diana Ross -- is the first taste of a full-length duets album slated for release later this year.
The E! series will follow the couple through the making of new music, and each episode will showcase a new song.
