It has just been revealed that Nicole and her Formula One ace boyfriend Lewis Hamilton recently ended their five year romance, after finding it increasingly difficult to spend time together.
But she put on her a schermazing brave face at the final set of 'judges room' auditions in the Welsh capital, getting to grips with a cake made of her favourite balls.
The former Pussycat Doll turned 35 on 29 June, and was presented with the chocolate treats by the 'X Factor' crew.
As she arrived at the Mercure Holland House Hotel she wowed the waiting crowds in a red HUGO trouser suit and white crop top, which bared her toned tummy.
Tryouts for the tenth series are set to continue with the 'arena auditions' round later this month, as part of the new 'double auditions' process.
