S Club 7 star Jo O'Meara says she has called off her engagement to fiance Lee after a series of rows.
The couple agreed to tie the knot in October 2000 and were to set a date this year.
But Jo admits her busy schedule has taken a toll on the relationship and the wedding is now off altogether.
She told the Sun: "We're still together. We had problems over Christmas and wanted to ease the pressure. I'm sure we'll get married but not yet.
"Things just got too much for us. We are still very close."
Jo has never revealed Lee's surname and is rarely pictured with him, to protect his privacy.
Her decision to call off the wedding means Rachel Stevens is the only engaged member of the band.
Last month she agreed to marry Holby City star Jeremy Edwards.
