The star's publicist said there was "no truth" in the rumours that she was pregnant with husband Guy Ritchie's baby.

A UK magazine claimed Madonna, 44, had visited a birth clinic in London three months into her pregnancy.

It quoted an unnamed source which said the singer was investigating self-hypnosis for the labour.

But her UK spokeswoman Barbara Charone flatly denied the story had any basis of truth and said that the same false rumour was often circulated.

Guy Ritchie and Madonna married in 2000

Madonna already has two children, Lourdes, six, and two-year-old Rocco.

She has recently denied rumours that she is quitting Britain to move back to Los Angeles.

Madonna settled in the UK following her marriage to Lock Stock and Two Smoking Barrels director Ritchie in 2000.

Recent reports suggested she wanted to move back to America so her children could be schooled there.

But a spokesman for Ritchie said the couple split their time roughly evenly between the UK and the US and they still had a love for all things British.
