TVLine Items: John Legend In, Lionel Richie Out on ABC's Duets, Hot Newsroom Promo and More

John Legend has replaced Lionel Richie on ABC’s new competition series Duets.

The Grammy-winning recording artist will serve as a mentor and singing partner to aspiring musicians alongside fellow stars Kelly Clarkson, Jennifer Nettles and Robin Thicke.

Duets finds the four pros (which now include Legend) traveling the country to recruit two proteges each. Once chosen, the superstars will duet with their mentees in front of a live studio audience each week, until only one contestant is named by both viewers and the mentors as the winner.

Richie reportedly bowed out due to scheduling conflicts.
