Despite the fact that the onetime pop singer andNewlywedsstars latest album,Do You Know, debuted at No.

1 on the country charts last September, the disc ultimately proved underwhelming with sales stalling out around 180,000.

She was only on loan to Sony Nashville for her country album.

(A rep at Epic confirmed that.

As for Simpsons next album, her personal publicist said they dont know what genre shell tackle.)

When contacted, an ABC rep would only say, We do not comment on casting rumors.

What about another singing cameo on the show, then?

That would be unlikely, claims a second show source.

She appeared last season, on September 30, 2008, and sang two songs, says the insider.

I doubt wed have a repeat performance so close to her last one.

Itll take more than that to beat down the bloggers.
