Will Britney Spears Show Up at the Grammys?

The 53rd Annual Grammy awards air Sunday night, and as usual, the show will rock, producer Ken Ehrlich promises CNN.

For starters, there's a tribute to Queen of Soul Aretha Franklin featuring Christina Aguilera, Jennifer Hudson, Martina McBride, Yolanda Adams and Florence Welch from Florence and the Machine.

"Every one of these women can sing, and we wanted to keep it all women because Aretha broke so many barriers and so many boundaries for women that this is a little payback," says Ehrlich, adding that they'll perform hits such as "Respect" and "Natural Woman."

Franklin, who had surgery in December for an undisclosed health problem, knows who is involved, and, Ehrlich tells CNN, "She's very happy about everybody, and she keeps saying to me, 'OK, you can have them this year, but I'll be around next year.'"

That's not the only collaboration happening that evening. Gwyneth Paltrow and Cee Lo will reunite to perform his hit "Forget You" -- and the Muppets will join them.

Says Ehrlich, "This is all Cee Lo. He came to us and said, 'You know, when I was growing up, I loved 'The Muppet Show.' I remember Elton John on 'The Muppet Show.' That's what I want to do.’"

While Ehrlich reveals that "fans' jaws will drop" when they see Katy Perry's music number, he won't confirm reports that Britney Spears will appear on the show.

"I have no comment," he says. "Nothing to say about that."

Guess we'll find out when the Grammys air February 13 at 8 p.m. on CBS.
