Emma Willis has suggested that Madonna could take Kylie Minogue's spinning chair on The Voice - if she has a space in her diary.
The host of the BBC singing contest described Minogue as "the loveliest, warmest, kindest" woman, and said she will be difficult to replace.
The Australian pop star quit The Voice after one series to concentrate on her own music career.
She thanked fans for their ''incredible support'' and confirmed she would not return for the next series, leaving a space on the panel.
Willis told the Mail on Sunday's You magazine: "We were lucky to have her last year. She was my idol as a teenager - I had the perm - so I was nervous about meeting her; but she puts you at ease. She's the loveliest, warmest, kindest person."
Considering a possible replacement, Willis said: "There's always Madonna, if she's not busy!"
Willis, who also presents Big Brother, told the magazine that swearing is her "guilty pleasure".
She said: "I can't swear at work or at home, so when I go out, I really swear!"
The Voice host said approaching her 40th birthday does not worry her.
The 38-year-old said: "I see women who get hotter as they reach 40: Liz Hurley, Victoria Beckham. And I feel I'm being taken more seriously in my career as I head closer to 40."
