There will be no wedding for pregnant singer Charlotte Church – for now, at least.

Church, 21, on Monday denied tabloid reports that she is set to marry her rugby-star boyfriend Gavin Henson, 25, next month in a castle near her home in Cardiff, Wales.

A rep for the singer tells PEOPLE: "This is definitely not true."

Earlier this month, Church revealed she is pregnant with Henson's baby. The couple live together and have been dating for about 18 months.

Church, who has her own late-night show on British TV, first found fame at age 13, when her 1999 debut album Voice of an Angel' sold more than three million copies worldwide. Her audiences have included Bill Clinton, Pope John Paul II and Queen Elizabeth II.
