Courteney Cox is reportedly dating Snow Patrol musician Johnny McDaid.

The 'Cougar Town' actress was accompanied to her friend Jennifer Aniston's Christmas party on Sunday (08.12.13) by the pianist-and-guitarist and onlookers at the bash say they were inseparable for the entire evening.

One source told Life & Style magazine ''They arrived around 7pm and left together about three hours later. She drove and he sat in the passenger seat.''

Another source added: ''Courteney definitely looked like she was on a date! They were holding hands during the party.''

While it is unclear how the 49-year-old actress - who has nine-year-old daughter Coco with ex-husband David Arquette - and the 37-year-old rocker met, they are both friends of 'A Team' singer Ed Sheeran, sparking speculation he may have played matchmaker between them.

Ed took to Twitter recently to drum up support for Courteney to win a People's Choice Award for her role in 'Cougar Town'.

He tweeted: ''My friend Courteney is nominated for a People's Choice Award for favourite cable TV actress. She's never won one before, and she lets me live in her beach house, so how's about we all vote for her and win her the ... thang eh? Safe. (sic)''
