Singer Ed Sheeran is likely to be the best man at the wedding of actress Courteney Cox and musician Johnny McDaid.

Sheeran had introduced the two and he is expected to take on the important role when the couple exchange vows later this year, reports femalefirst.co.uk.

"Not only is Ed great mates with Johnny, he is a close friend of Courteney's. Ed said yes immediately when asked. Johnny's other best pal, singer Foy Vance, is also an usher," said a source.

"It's between him and Ed for best man - they'll probably share it," added the source.

McDaid proposed to Cox, who has 10-year-old daughter Coco with ex-husband David Arquette, in June after just six months of dating.
