Faith Hill and Tim McGraw duetted for the first time ever in the UK when they took to the stage at C2C festival in London on Friday 9 march.

The married country music powerhouses kicked off the annual three-day music extravaganza at London's O2 Arena and delighted fans with their Soul2Soul tour setlist, including hits Break First, Piece Of My Heart, Wild One and Just Breathe.

Hill and McGraw have been married for 21 years but their chemistry was electric on stage, with the couple lovingly gazing into each others' age at every opportunity.

McGraw even joked that he won the staring contest, telling the crowd: "I won the stare down contest tonight. For all the husband's out there - can I get an amen?"

They also performed their defiant hitTelluride, and McGraw kneeled in front of wife when they belted out Aretha Franklin and George Michael duet I Knew You Were Waiting (For Me).

Earlier in the evening, Kelsea Ballerini played her first ever UK gig on the main stage, while Brett Young took to the spotlight stage between Kelsea's performance and Faith and Tim's.

Country To Country continues at London's O2 arena this weekend, with Kacey Musgraves headlining on Saturday 10th March and Little Big Town on Sunday night.

Una Healy of The Saturdays will take to the Town Square Stage on Saturday and at C2C close-Up Sunday morning.

The Irish singer is set to perform hits from her new album, and recently admitted fans will be surprised to hear new direction.

She told the MailOnline: “II’ve stepped it up a notch with more attitude, and I’m not holding back with the lyrics so it’s a bit more rocky as well.
