Bono photobombs Irish couple's wedding in Dalkey, Dublin (Photo: Carol Ryan)

The happiest day of one Irish couple’s lives took a surprising turn when U2’s front man, Bono, photobombed their wedding photos in Dalkey in south County Dublin.

Sinead O’Sullivan and David O’Connor were just finishing up their wedding photo shoot in Bono’s neighborhood when they bumped into the Irish rock star.

Their photographer Carol Ryan told the Irish Independent the couple were “stunned,” but found him “very charming.”

Ryan explained, "He was walking with his daughter (but) he was happy to jump into some shots."

The newlyweds were delighted with their extra “special memento” and impressed by how “nice” the rock legend is.
