Courteney Cox and Ed Sheeran
This is one famous friendship that we did not see coming. British singer-songwriter Ed Sheeran began his kinship with Courteney Cox when they were introduced by a mutual friend in 2013. Shortly after that, he ended up living at Courteney's Malibu, CA, beach house for three months while writing music. He told The Sun that year, "There was no rent, but I made the bed and cups of tea and things like that. If you're staying at your friend's house, you should treat it like your own." Ed quickly repaid the favor in another way when he introduced Courteney to her now-fiancé, Snow Patrol's Johnny McDaid.
