Madonna is currently touring in the US
Madonna has said she is grateful her workload is distracting her from her divorce from film-maker Guy Ritchie.
"I'm sad about my personal life, but I feel very blessed and very lucky that I have the opportunity to do what I do in my professional life," she told AP.
She added: "It would be horrible if I was just thinking about getting a divorce and had nothing to do."
Madonna, 50, and Ritchie, 40, divorced in London last Friday after eight years of marriage.
Tour and movie
She is currently touring the US with her Sticky & Sweet concert, and has also produced a documentary I Am Because We Are, which is being released in cinemas on 1 December.
The film looks at the fight against Aids in Malawi, the home of her adopted son David Banda.
It has been reported that Madonna and Ritchie did not demand a financial settlement from each other. Madonna is thought to be worth some £300m, while Ritchie is believed to have £30m in assets.
The couple are also reported to have agreed to share custody of their two boys, eight-year-old Rocco, and three-year-old David, while Madonna's daughter from an earlier relationship, 12-year-old Lourdes, will stay with her.
