Madonna is sorry for letting her Aussie fans down by cancelling her proposed Aussie tour to head home to her kids.

Madonna is sorry for letting her Aussie fans down by cancelling her proposed Aussie tour to head home to her kids.

Madonna has apologised to her Australian fans for choosing motherhood over her music.

Even though no official dates for the Australian leg of her MDNA tour were ever announced the Material Girl has recorded a personal message for her fans to say sorry for bypassing the land down under, yet again.        

"I know the last time I was on tour I missed Australia as well. I can promise you in my heart of hearts it was my intention to come again, but like the last time my children are my first priority," the single mother of four said.

"My daughter's going to be leaving home soon, she's 16-years-old and it was a really hard decision for me to make," she said referring to her eldest daughter Lourdes Leon.

"I have two scales I have to weigh in front me of me, my job as a singer and entertainer and my job as a mother. Because my children are older I can't take them on the road with me everywhere. At the end of the year I really feel I would be an irresponsible parent if I didn't stop my tour and spend time with them."

The apology follows a tumultuous year for the pop star, both on the road and at home.

Her parenting skills were the subject of speculation when Lourdes was photographed smoking in New York earlier this year.

"I'm probably not as tough as I should be. I think I need to be maybe tougher," she told the Today show in the US back in April.

"To be a single mother of four and to work as much as I do, with my life in a kind of metaphorical fishbowl, it's pretty challenging. But so far I've survived with sanity and humour intact."

According to various reports over the years Madonna's children, including 12-year-old Rocco, whose father is film director Guy Ritchie, 5-year-old Mercy and 7-year-old David have all been raised under strict Kabbalah rule which forbids TV and sees them all follow a macrobiotic, vegetarian and organic diet.

Madonna apologised to those who were "angry, upset and disappointed" with her for cancelling what would have been her first Australian tour in 19 years.

"I did everything I could. I decided that the best thing for me to do would be to end my seven months on the road at the end of the year and not continue on with my tour so I could spend time with my children who need me."

She promised an Australian visit is still on the cards.

"When I do come to Australia I would have made the wait worth your while," she said.

Since kicking off in Tel Aviv in May the MDNA tour has received lacklustre reviews with Madonna gaining more headlines for her political statements rather than her performances.
