Colin's in the driving seat as his brother toasts year of marriage

Loved-up couple Eamon Farrell and artist Steven Mannion enjoyed a night to remember last night, celebrating the first anniversary of their wedding blessing at the Harcourt Street club.

The Diary can reveal how the high profile pair hired out the venue in order to play host to a select group of friends and family as they also toasted Eamon's 42nd birthday.

And there was no shortage of star guests in attendance, with the red carpet rolled out for Hollywood hunk Colin, Eamon's younger brother, who arrived to the hotspot with his mother Rita and sister Claudine shortly after 9pm.

The actor was designated driver for the night, chauffeuring his mum and sister to the venue in a silver four-wheel drive.

And while there was plenty of interest from intrigued passers-by when they spotted the A-list movie star dressed down in jeans, a checked shirt and a black leather jacket on Harcourt Street last night, there was no chance of any gatecrashers getting in, with Eamon and Steven organising extra security for the swish party.

"Krystle was not officially open last night so they had the place to themselves," said an insider.

"It was a small and intimate gathering for the couple's close friends and immediate family and they were delighted that the club was closed to the public as they deliberately wanted to keep it low-key and a private affair.

"Staff at the club were under strict instructions to let in only those whose names were on the guestlist and there were no exceptions.

"Obviously the last thing anyone wanted was for Colin to be mobbed at his own family do," they added.

Among the guests who attended the VIP soiree was Krystle's glamorous co-owner Eileen Wright and of course Eamon's first cousin and Colin's godmother Martina Fox and her hubby Robbie.

Other attendees at last night's party included friends of the grooms such as Izabela Chudzika, Breffny Morgan and Catriona O'Connor.

Eamon, who runs the National Performing Arts School, and his artist partner Steven have been together for more than six years and cemented their union the summer before last.

The couple flew to Vancouver in Canada for a same-sex marriage ceremony but waited until this time last year to formally mark their nuptials with a blessing and a reception afterwards at Krystle, as they both wanted Eamon's younger brother Colin to be there.

The In Bruges actor (34) will remain in Dublin until next week, having spent the past few days at his family home in Castleknock, where his mother Rita hosted Christmas dinner for seven people.

His two sons, James (7) and Henry (1), are spending the holidays with their mothers, Kim Bordenave and Alicja Bachleda-Curus in Los Angeles and Poland respectively.
