Mum-of-one Dannii (41) has been unveiled as the new judge on Sky Living's Britain & Ireland's Next Top Model.
It comes at the same time as Cowell has reportedly been trying to convince Dannii and Cheryl Cole (29) to return to X Factor.
Cowell is due to arrive in the UK for "crisis" talks with ITV bosses about the struggling series.
Cowell is looking to make major changes to the format for next year's series -- and a return for Dannii and Cheryl has been long mooted.
But Cheryl told Graham Norton on his BBC show there was "no chance" that she would take a seat next to Cowell on the panel.
