Dannii Minogue looks amazing at one of her first appearances since split

Dannii Minogue looked radiant despite having had a few rough months after splitting with Kris Smith

Dannii Minogue has had a rough couple of months, first she split with boyfriend Kris Smith, then the world found out that she had slept with Simon Cowell, but the trooper showed no signs of heartache at a photocall yesterday.

Ms Minogue, 40, looked radiant and super-svelte in a white, lace, dress from her own Project D collection at an event to promote cosmetics company ModelCo in Sydney.

The former X Factor judge did however make it clear to the press in attendance, via her management, that she would not be answering questions about reports that she and Smith were considering a reunion for the sake of their son Ethan.

She also managed to avoid commenting on why she turned down another stint as a judge on the UK version of the X Factor, but the recent confession by Simon Cowell in his tell-all book that he and the Australian had a fling years ago might have had something to do with it.

It's also understood that Dannii turned the gig down in order to be able to spend more time in Melbourne where she and son Ethan are based.

With Dannii Minogue out of the picture, who should be the fourth X Factor judge? Let us know in the comment box below.
