It's official! Louis Walsh signs X Factor contract as Nicole Scherzinger favourite to replace Rita Ora
Louis Walsh has signed on the dotted line to return to The X Factor.
Louis is the third official addition for the upcoming series along with presenter Dermot O'Leary and boss Simon Cowell.
On Tuesday Rita Ora announced she would not return to sit on the judging panel for a second year as she focuses on music and acting.
Given fellow judges Nick Grimshaw and Cheryl Fernandez Versini's earlier departure, there are now two vacant slots to be filled.
As Cowell goes back to basics with the new series, following a disastrous run last year, it looks like former judges Nicole Scherzinger and Sharon Osbourne may be in the running for a comeback.
Scherzinger was last on the panel in 2013 while Sharon was on the panel from 2004 to 2007 and also in 2013.
Sharon's involvement, however, may be in jeopardy as she is currently in the midst of dealing with marriage difficulties, reportedly due to her husband Ozzy having an affair.
Neither Nicole nor Sharon's involvement has yet been confirmed.
