Ball will also host two specials, including a BBC TV show celebrating Elaine Paige’s 60-year career in showbusiness with a concert.
On Tuesday, the BBC said from May the 54-year-old radio DJ and presenter will host a new weekly show, from 1pm to 3pm on Saturdays.
Ball left her Radio 2 breakfast show at the end of last year, with Scott Mills taking over in January.
Zoe Ball is to return to Radio 2 with a weekend show, the BBC has announced.
