Kelly Clarkson is to miss the Grammy Awards to appear on 'American Idol'.
The 33-year-old singer is expecting her second child and has been advised by doctors not to make two gruelling trips from Nashville to Los Angeles so close together.
And so, despite being up for Best Solo Performance for 'Heartbeat Song' and Best Pop Vocal Album for 'Piece by Piece', Kelly - who already has 19-month-old daughter River Rose with husband Brandon Blackstock - is shunning the prestigious awards ceremony in order to be a guest judge on the show where she became famous in 2002.
Speaking on 'On Air With Ryan Seacrest', she said: "I was going to do the Grammys and 'Idol', and then my doctor was kind of like, I just have such hard pregnancies, flying back and forth to LA, like if they were closer together, I would've done both, but I had to kind of choose one.
"I obviously chose 'Idol' because it's ending and I was the original winner, so it'd kinda be weird if I wasn't there.
"I'm unfortunately going to have to miss the Grammys."
It was announced last month that the 'Breakaway' singer would be making a special appearance on the 15th and final season of the talent show.
;American Idol' executive producer Trish Kinane said: "We've invited her to be part of this season and she's really happy to be.
"She will be a guest judge on our first live top 10 show and she'll also perform."
