X Factor judge Dannii Minogue split from her male model boyfriend over her constant work commitments, it has been claimed.
Dannii, who quit The X Factor last year due to clashing schedules with Australia's Got Talent, has been absent from Kris and their son Ethan for months.
Kris even reportedly brought Dannii a passport holder for Christmas as a "dig" at her constant traveling.
The Aussie star has not only been taking part in auditions for the new series of AGT, but has also been filming in South Africa and has recently spent time in the Hayman Islands as part of her promotional work.
“There have been lots of problems and the pair were living increasingly separate lives," a source told the Daily Mirror today.
"Dannii is a workaholic, Kris wanted her to slow down and enjoy life a bit more, but you don’t tell a Minogue that.
"Dannii is a perfectionist – she lists everything around the house like chores on little Post-it notes – they are everywhere and when things are tense this kind of thing can cause a row.”
Confirming their split after four years together this week, Dannii posted on Twitter: “It brings me great sadness to tell you that Kris & I have separated.
“We still care for each other & ask for privacy at this difficult time, in particular for our son Ethan who remains our number one priority.”
Kris wrote on Twitter: “Dannii and I have a deep mutual love and respect for each other and although things have not worked out we have a gorgeous son together that we both love.”
