Singer Dannii Minogue and choreographer Brian Friedman are to be judges on the next series of The X Factor.
Dannii Minogue has scored 13 UK top 20 hit singles
The pop star and Friedman - a panellist on current talent show Grease is the Word - will fill the gap left by the departure of Louis Walsh.
They will join long-standing judges Simon Cowell and Sharon Osbourne on the ITV programme.
Earlier this year it was announced that Dermot O'Leary would present the next two series, replacing Kate Thornton.
Minogue, 35, who has scored a string of chart hits, said: "I can't wait to be part of The X Factor team and getting up close and personal on a daily basis with Simon.
"Just because I'm the new girl, I won't be a pushover - he'll soon see my competitive streak."
Friedman, who has worked with Britney Spears, said he was "flattered to be offered such a coveted position".

ITV's director of comedy and entertainment, Paul Jackson, said: "We're delighted we've managed to secure two new judges who between them have such a wealth of talent and experience."
The programme's format is also being revamped for the next series, with the introduction of a new performance category.
The age limit for hopefuls has also been lowered.
