Johnny McDaid and Courteney Cox received several engagement presents in his native Northern Ireland

The trio reportedly received unique matching rings made by a designer in a local jewellery shop.

An insider said: "[He] thought it would be nice for them to have [it] as a souvenir. They are the loveliest couple and are so down to earth that they did not mind getting photos or talking to us."

The source added: "Coco was great too. She loved the city also and was spending quality time with Johnny's two sisters. They were all so happy."

The famous couple then visited a nearby gift shop, where Coco, whose father is the former 'Friends' star's ex-husband David Arquette, was presented with another special gift after they posed for more pictures with fans.

An eyewitness told UsMagazine.com: "Coco loved it. She was saying how much she loved emeralds, so shop employees gave her an emerald-and-silver shamrock necklace as a souvenir."

Another fan said: "It was such an exciting time for us because our city is small, homey and compact. We never get big stars like Courteney Cox. It was great!"

A source previously revealed the couple are thinking about getting married in Northern Ireland and flew there to celebrate their engagement with Johnny's family.
