The former Dancing With The Stars contender began dating stockbroker Adam Bidwell, a close friend of British royal Prince Harry, in February, but they have decided to go their separate ways.
According to the Daily Mirror, the pair's relationship became strained after Bidwell began spending more time in the gym shaping up for an upcoming charity boxing match.
A source tells the tabloid: "Adam has been training really hard for this boxing match and has been really under the cosh (under pressure) at work. It was Katherine's decision but she still loves Adam and will continue to support him as a friend. Despite this she is incredibly sad and feeling pretty raw - splitting up is always painful."
The romance was Jenkins' first since she called off her engagement to Welsh TV host Gethin Jones in December 2011.
