Dannii Minogue in 'constant contact' with former 'X Factor' acts

Dannii Minogue keeps in "constant contact" with her old 'X Factor' acts.

The 41-year-old singer was a judge on the show from 2007 to 2010 and has managed to keep in touch with the likes of Stacey Solomon, who says the 'X Factor' Australia panellist is always on the phone to her to find out how she is getting on with her children, Zachary, five, and 14-month-old Leighton.
