Madonna finds being a single mother ''hard work''.

The 'Give Me All Your Luvin' singer - who is currently dating dancer Brahim Zaibat - has four kids, Lourdes, 15, Rocco, 12, David, six, and five-year-old Mercy and admits juggling raising them and maintaining her busy career can be difficult.

She said: ''I'm not going to lie - it's hard work having four kids and doing all the work I do.

''Everybody has something to say about the way I live my life. At the end of the day I'm doing my best. If people don't like it, then that's really their problem.

''Sometimes I cope with it very well, sometimes it's a struggle. It's a challenge juggling everything -- multi-tasking is my middle name.''

The 53-year-old singer also revealed her kids try to outsmart her by speaking to one another in French because they know her grasp of the language isn't as good as theirs.

She added in an interview with The Sun newspaper: ''We just try to have as normal a life as possible. My life with them at home is really just about schoolwork and health and the after-school lessons just like everybody else.

''Most of them go to a French school. My French is not very impressive, but it's good enough. Everyone in my house speaks perfect French but me. I'm getting better at understanding when they're not talking about their homework.

''I'm now picking up things and saying, 'What did you say?'. I know the necessary swear words, so they have to be careful.''
