The former Cork hurler and footballer (38) and his long-term girlfriend Siobhan Quirke begin the New Year as a married couple when they wed in a ceremony in Rochestown Park Hotel in Douglas.
Players from GAA club Na Piarsaigh provided a guard of honour with hurleys inside the chapel for the loved-up pair after they exchanged vows.
Sean Óg and Siobhán - along with other members of the wedding party - performed an indigenous Fijian Rotuma dance inside the chapel.

The Fijian-Irish footballer proposed during a romantic trip to New York in November 2014 and the bride-to-be posted pictures of her sparkler on Facebook.
Brainy Siobhan recently relocated to London, where she is continuing her studies with UCD’s Smurfit Business School after landing a coveted Bord Bia Marketing Fellowship.
Seán Óg made his Cork debut in 1996 and was awarded the Freedom of the City in 2011 and he also published his autobiography in 2012.
Ó hAilpín isn’t the first GAA star to wed this week as former Kerry footballer Paul Galvin and Dublin Captain Stephen Cluxton also tied the knot in New Year's ceremonies.
Galvin wed Today FM star Louise Duffy in a New Year’s Eve ceremony in Crossmolina Co. Mayo yesterday attended by more than 200 guests, while Cluxton married his girlfriend of five years Joanne O’Connor in Killenard yesterday afternoon.
