The stars joined forces for a rendition of Snow Patrol's 2006 hit Chasing Cars and a cover of Stevie Wonder's funk classic Superstition for Brid MCDaid's wedding at Beech Hill Hotel in Ardmore, Northern Ireland on Friday (26Aug16).

Johnny's fiancee, Friends actress Courteney Cox, and her 11-year-old daughter Coco also attended the festivities.

Courteney and Johnny, who were introduced by Sheeran, now look set to follow Brid in tying the knot, having reconciled earlier this year (16) after breaking off their engagement in November (15) following an 18-month romance.

The actress recently opened up about the couple's temporary split to adventurer Bear Grylls while tackling rural Ireland on his survival show, Running Wild With Bear Grylls.

"We were engaged for over a year and then we broke up," she revealed, before adding, "I definitely have learned a lot, and no matter what, I will be a better person from that break-up, even though it was so brutal."

The couple's relationship now appears to be back on track and one onlooker, who spotted the pair in Johnny's home town of Derry, Northern Ireland on Saturday (27Aug16), assumed it was Johnny and Courteney who had recently wed.

"They (Johnny and Courteney) seemed very at ease with one another," the local told the Irish Mirror newspaper. "Someone came over to speak to them and I heard her (the fan) congratulate them and they were smiling and laughing. I presumed they must have got married already. They are a lovely couple."
