Whitney Houston will make her long-awaited comeback on the forthcoming series of The X Factor, according to reports.
The singer is set to perform her new single on the programme in October, as well as hold a masterclass for finalists.
A source told the Daily Mirror: "Simon Cowell is cock-a-hoop."
A host of big names, including Madonna and Rihanna, are also reported to be making guest appearances on the new series, which starts on Saturday.
Meanwhile, the X Factor has come under fire from the performers' union Equity.
The body said the talent contest was guilty of "cheap exploitation" because it does not pay contestants.
