Katherine Jenkins and her dancing partner reportedly looked "very touchy-feely" over dinner this weekend.
The Welsh classical singer and television presenter Gethin Jones mutually decided to end their four-year relationship at the end of December.
Since their split, Katherine has signed on to perform with dance partner Mark Ballas in US TV show Dancing with the Stars.
Katherine and Mark appeared to be more than colleagues while dining out with pals Saturday at London's Brompton Club.
"[They were] very touchy-feely," a source told British newspaper the Mirror. "It all looked very flirty and he was very tactile which she didn't seem to mind."
Mark seemed incredibly taken by his gorgeous date.
"He certainly looked pleased with the company, and there was a lot of attention when people noticed her with a mysterious new man," the source explained.
Katherine's representatives insist that she and Mark are just getting to know each other before their four-month stint as partners on the show.
Katherine was with her ex-fianc Gethin for four years before they called it quits three months ago.
The songstress will begin filming Dancing with the Stars with Mark on March 19.
