They got on really well and quickly developed feeling for each other.
Lives are changing forever for many of our soap favourites as Aaron Dingle has a wedding the day before he goes to prison in Emmerdale and Leanne Tilsley’s baby arrives in Coronation Street – under dramatic circumstances, of course!
In East Enders, Ian Beale faces the prospect that he may be seriously ill while in Hollyoaks, John Paul Mc Queen and Ste Hay prepare to leave their respective partners and Connie Beauchamp is on the verge of a shocking decision in Casualty. There are also two hostage situations, some serious passion, a violent outburst and a tragic goodbye.
They both know that people will be interested in what is going on, but they don’t mind." Oh, we love a good romance!
Daniel, who has played vicar Billy Mayhew in the soap since 2014, shared a cute snap of the two on the the way to the awards with the hashtag "Suited and booted", whereas Rob, 25, tweeted about attending the event with "notorious homosexual" Daniel!
