All Together Now, as we congratulate a couple who have a major reason to celebrate this bank holiday weekend.

Philip O'Sea and Rosin O'Brien joined the crowds in Waterford on Friday to watch Fontaines D.C. take to the stage, but little did she know that it would shape up to be a life-changing day.

With the sun shining down at Curraghmore Estate, Philip got down on one knee and asked her to be his wife.

Photos taken by Aiesha Wong who caught the moment on camera show the thrilled couple posing with Philip still on bended knee holding his future wife's hand.

Roisin was looking summery in a short gingham swing dress as they posed for their engagement snaps.

'A lovely day for a proposal. A huge congratulations to Philip O'Sea and Roisin O'Brien from everyone at All Together Now,' a post on the festival's official account reads.

Revellers were thrilled with the news, with one person commenting: 'Class... congratulations to you both, absolutely delighted for ye.'

Someone else added: ' Congratulations lads... brilliant pic to have'

Congratulations, Roisin and Philip!

Elsewhere, Carl Mullan's All Together Now experience got off to a rocky start when he found himself 'locked out' minutes before they were due to go on air at the festival.
