The pair, who are thought to have split on New Year's Day, have blamed conflicting work schedules.
'Ricky Groves and Hannah Waterman have announced today that after much consideration they have decided to formally separate,' a spokesman tells The Sun.
'Both their careers have been hugely successful, but for most of last year their work has kept them apart.'
Ricky, 41, who met Hannah, 34, while starring in EastEnders, has now moved out of their marital home near Huntingdon, Cambs.
They have vowed to remain friends.
Ricky and Hannah - who has lost 3st in 5 months - got engaged in 2005 and tied the knot the following year.
