Dannii Minogue's son gives her a ''reason to get up and keep going''.

The Australian singer split from Kris Smith, the father of two-year-old Ethan in April, and though she insists reports they have reconciled are untrue, they will always work together to do the best for their little boy.

She said: ''I'm extremely private about my relationship, but I will tell you nothing has changed since Kris and I announced our separation.

''Although we are separated, Ethan remains our priority. We just celebrated his second birthday yesterday and I'm loving every minute I get to spend with him.

''Motherhood has been the most wonderful experience for me; his smile makes any bad day right.

''He's just adorable and gives me a reason to get up and keep going.''

Earlier this year, it was claimed 40-year-old Dannii had a secret relationship with Simon Cowell when they worked on 'The X Factor' together.

Though the brunette beauty didn't directly confirm the claims - which were made in Tom Bower's biography 'Sweet Revenge: The Intimate Life of Simon Cowell' - she admits they make for a ''great read'' and described the author as a ''respected journalist''.

She told the New Edition of Britain's Glamour magazine: ''I haven't read the book but I've been told about the excerpts that relate to me and the speculation of my private life.

''From what's been reported, they [Tom and Simon] put hundreds of hours into making this book, and Tom is a respected journalist.

''They looked very pleased with it all at their launch. I'm sure it makes for a great read and I wish them the best.''
