The Material Girl is a mother of four, and sometimes it can all be overwhelming.

"I'm not going to lie, it's hard work having four kids and doing all the work I do," Madonna, 53, said in an interview with The Sun, a British publication.

The twice-divorced pop star, actress and filmmaker told The Sun that her experiences with single motherhood have influenced her upcoming album,  MDNA.

Her 12th studio album, MDNA is slated for release March 26.

The singer's divorce from her second husband, director Guy Ritchie, is referenced on some of the tracks.

She raps about the "life of an ex-wife," with its fast-paced schedule, lack of time, pre-nups and custody.

In lyrics for the song "I Don't Give A," Madonna mentions trying to "be a good girl," trying to "be your wife," and trying to be all  "you expected of me."

And in the track "F***ed Up," she appears to accept some responsibility for what happened, singing, "I blamed you when things didn't go my way. I could have just kept my big mouth shut."

Whether Madonna remains single for much longer could be in question.  Her boyfriend, 24-year-old Brahim Zaibat, has reportedly asked her to marry him.

A report in the British publication, The Daily Mail, claims the French dancer proposed in February.

Madonna reportedly asked for time to consider the proposal.

The two have been dating for two years, making it work despite their 29-year age gap and differences in religion. Zaibat is Muslim and Madonna follows Kabbalah, an ancient mystical Jewish tradition.

In an interview with ABC News earlier this year, Madonna acknowledged missing certain aspects of marriage, such as "being a part of a family unit" and "not having to make all the decisions on my own."
