Lovefest: 5 Couples Get Engaged at Ed Sheeran's London Concert

— -- There was nothing but an arena full of love at an Ed Sheeran concert in London this week that saw not one, not two, but five marriage proposals.

“Ed looked absolutely chuffed,” concertgoer Alexandra O’Connor told ABC News today. “So chuffed he invited himself and all 18,000 of us watching to all five weddings.”

O’Connor, who lives in Essex, England, was listening to Sheeran sing “Tenerife Sea” Monday night at London’s O2 arena when the romantic spate of proposals broke out.

“During the song, a young man got down on one knee,” O’Connor recalled by email. “Seeing the instant recognizable symbol for 'Will you marry me?,' the whole crowd around the couple started to scream and cheer.”

“Once Ed had finished his performance, he said, ‘…Did someone just propose?,’” O’Connor said. “Instantly our whole area started cheering and as the couple was standing and waving everyone around got their lights on their phone to make the couple more visible to Ed.”

“Ed responded with, ‘That’s so cool,’” she said.

Just a few songs later, during a performance of the aptly titled “Give Me Love,” O’Connor says four more couples got engaged.

“Throughout the romantic song, random bursts of cheers were coming from different areas of the arena,” O’Connor said. “It was fantastic.”

One of the newly-engaged couples was captured on camera by a fellow concertgoer who took to Twitter to share a photo of their happy moment.

In addition to shouting out early wedding invitations for the five couples, Sheeran gave the lovebirds some advice, according to O’Connor.

“He also added, ‘If you have babies, and I'm not saying to start trying right now, but, when you do, remember that Ed is a great name,’” she said.
