Sean O’Brien Celebrates Wedding with Rugby Legends in Kilkenny

UPDATE: Rugby star Sean O’Brien tied the knot with Eloise O’Brien on December 30, 2025, in a lively ceremony in Kilkenny, bringing together rugby legends for a celebration filled with joy and country flair. The wedding, held at a traditional church, was followed by a vibrant reception featuring a Yellowstone theme that ensured a memorable end to the year.

The event saw notable appearances from fellow rugby icons Conor Murray, Paul O’Connell, and Peter O’Mahony, who joined the festivities, honoring their long-standing friendship and camaraderie on and off the field. The reception featured a unique Bucking Bronco, where Eloise showcased her adventurous spirit, much to the delight of Sean, who watched with laughter.

Guests embraced the couple’s rural roots by donning cowboy hats and boots, aligning perfectly with Sean’s nickname, the Tullow Tank. The couple, who share a son named Jack, also made sure their little boy looked dapper in his pageboy outfit during the church ceremony.
