The It's Not Unusual hitmaker publicly shamed BBC bosses on social media for telling him he was fired as a judge on the show only the day before they announced Faith and Boy George as replacements, despite Jones declaring an interest in returning for a fifth year.

However, he proved there is no bad blood with the new coach on Wednesday night (27Aug15) by cheering Faith on at a small gig for 500 fans at The Savoy Hotel in London.

Faith rattled through her hits and performed covers of Sinead O'Connor's hit single Nothing Compares 2 U, Etta James' At Last, and River Deep, Mountain High by Ike and Tina Turner.

She says, "Performing tonight was an incredible experience - from the intimate crowd to the beautiful venue. I love performing in my home city, and it's always great to be able to do something special for some of my biggest fans. It was great to be able to create a jazz club atmosphere and perform songs that I wouldn't normally, in relaxed surroundings."

The gig was part of MasterCard's Priceless Surprises drive. Faith teamed up with MasterCard bosses earlier this year (15) to put on a concert for just two fans in an underground bank vault in London.
