The classical music star thanked fans for their support following the end of her ten-month engagement to Jones last month.
"Thank you for all your kind messages & concern," she wrote today (January 23). "I haven't deserted you... Just taking some time but promise to be back here soon."
Jenkins previously credited fans with fuelling her desire to perform again in the wake of the separation.
"Everyone has been really amazing," she said. "I've had so many messages that have helped me. I don't think I could have got up on stage without that... my fans have been so loyal which is so lovely."

The couple are believed to have parted ways over Jenkins's "very demanding" career goals, though other insiders have claimed that they were never going to get married.
