file-Shania Twain

The That Don't Impress Me Much singer Shania Twain and record producer Robert 'Mutt' Lange have decided to end their marriage after fourteen years.

Shania's spokesperson confirmed the pair was breaking up, saying: "Shania Twain and her husband, music producer Robert 'Mutt' Lange, are separating after 14 years of marriage. This is a private matter and there will be no further comment at this time."

Shania, 42, and 59-year-old producer Robert first met in 1993 and married just six months later.

Rumours that their marriage was in trouble first surfaced in 2000, but the couple stayed together and moved to Switzerland shortly after reports surfaced.

Shania later admitted she had struggled to cope with fame, explaining: "I needed a break, physically and mentally. I needed to leave behind the whole 'Shania' thing and be myself."

Shania and Robert worked together extensively, with his producing and co-writing many of her hits, including, You're Still the One and Man! I Feel Like A Woman!.

The couple has a seven-year-old son, Eja D'Angelo.

Shania is due to release a new album and signature perfume later this year.
