The WHOLE AGAIN singer broke up with Cosgrave - dad to her nine-month old baby JOSH - in January this year (03).
But she admits she's far from ready to move on.
She says, "No, I'm not over it. I'm probably not going to get over it for some time. But that's normal though.
"It's all been very hard. A few weeks ago I was expecting to walk down the aisle with Fran this year, but that's all changed. Though I'm glad we put an end to it now rather than after the wedding - for all our sakes, including Josh's."
