The 24-year-old singer split from rugby star Gavin earlier this year, although they have remained in close contact for the sake of children Ruby, three, and 21-month-old Dexter.
Charlotte is now dating musician Jonathan Powell, although pals have revealed she still feels uneasy watching Gavin flirt with his partner Katya Virshilas on the British television show.
“She’s always glued to Strictly and finds their chemistry uncomfortable. She says she knows when Gav fancies someone. After their raunchy rumba last week, Charl asked, ‘What’s he playing at?’ She’s been calling him a lot,” a source told Closer magazine.
Katya is in fact dating fellow dancer Klaus Kongsdal, so there are no real chances of romance between her and Gavin. However, hunky sports star Gavin has confessed he finds her very appealing.
“I fancy her. Oh, I wish she was single. But unfortunately she’s already going out with a champion dancer... so there’s no chance. I’m devastated,” he lamented.
