I'm not sure they were in the process of divorcing a few months ago and each received their decree nisi's. Whether or not its all officially gone through yet we don't know. Alfie and Roxy are engaged and planning a wedding so it must be nearly all sorted. With their inevitable reunion on the cards though i guess maybe it wont go through and they'll reunite and cancel the divorce. Spare us all from having to sit through them re-marrying.
