The couple of five years are parents to kids Ruby, 2, and Dexter, 15 months.
UK newspaper The Daily Mail reports that the break-up has been confirmed by the singer’s rep, though no further details were released.
The paper quotes a source close to the pair as saying, “It is an incredibly sad state of affairs. Both Gavin and Charlotte are deeply distraught. But after a lot of soul-searching, they realised this is the best course of action for them and the children. It was a mutual decision.”
When Gavin, 28, proposed to Charlotte just last month he said, “We’ve had good times and hard times, but it’s mostly been good times and I think we’re meant to be together now for the rest of our lives.”
