'They kept it quiet for ages but are at last coming to terms with being a couple in public.'
Geordie star Dec dated TV actress Clare Buckfield for 11 years but they split in 2003.
Dec strenuously denied that he and Ali were lovers in 2007, but now both are said to have told their families that their professional relationship has become a personal one.
'They all know each other anyway,' the insider tells The Sun.
'To be honest, it hasn't come as much of a surprise to some because they'd always been close.'
