Mel B has reportedly split from her husband because they argued so much.

The 'X Factor' judge is believed to have walked out on Stephen Belafonte after a turbulent period in their relationship, and has admitted they have been having explosive arguments recently.

In an interview done before the couple are reported to have split, she said: '' I walked in p***ed off because I had a big row with my husband about stupid stuff. Sometimes he p***es me off like no other but he gets me.''

The former Spice Girls star wed the 39-year-old film producer in 2007, later giving birth to the couple's only child, three-year-old Madison, adding to her two other children Phoenix Chi, 15, and Angel, seven from previous relationships.

However, the couple are believed to have parted ways after huge rows last week which left the 39-year-old musician so stressed she suffered crippling stomach pains for which she was hospitalised, causing her to miss the penultimate episode of the 'X Factor' on Saturday (13.12.14).

A source said: ''Mel's marriage has reached crisis point - in fact it's on life support. She has told friends it is over with Stephen.''

The star sparked rumours the couple had broken up when she returned to the singing contest for the show's final on Sunday (14.12.14), where she appeared without a wedding ring; a move which an insider said was a ''symbolic gesture''.

The source continued: ''It was a very symbolic gesture when she removed her wedding ring before appearing on 'The X Factor' final on Sunday (14.12.14) night.

''She knew what she was doing and wanted to send Stephen a clear message about her feelings.''

It is currently unclear whether the pair have split permanently, but friends are said to have told Mel to spend some time away from her beau in order to figure out whether she wants to give their relationship another chance.

The source added to The Sun newspaper: ''Her stress levels are very high and most of her good friends and colleagues were encouraging her to take time out from Stephen.''
