Kelly has been dating former Gladiator David for six weeks, however it appears they have already called time on their romance.
Last week, Kelly and David enjoyed a romantic holiday in Miami and it is thought they spent Valentine's Day together after jetting to Los Angeles.
However, a source has now told The Sun that Kelly has ditched David because he seemed only interested in fame.
The insider said: "Kelly got tired of the relationship and David trying to hog the limelight."
Neither Kelly or David have tweeted about the rumoured break-up. Reveal contacted Kelly's rep but he had no comment to make.
On Friday - Valentine's Day - David shared a picture of himself and Kelly admiring a nighttime sky in LA. He commented: "Fabulous."
