NICOLE Scherzinger is to return as the latest guest judge for The X Factor auditions.

The former Pussycat Dolls singer (below) will join the panel for the final London heat tomorrow.

Scherzinger previously appeared on the panel in 2010 when she stood in for then judges Cheryl Cole and Dannii Minogue.

She joins a succession of guest judges who have joined the series this year until a permanent fourth judge is found to sit alongside Gary Barlow, Tulisa Contostavlos and Louis Walsh.

Yesterday, chart-topping star Rita Ora impressed show bosses when she featured on the panel, although she may not yet have a high enough profile to clinch the deal.

Her busy schedule and touring commitments may also affect her availability.
