Kelly Brook felt "hurt and humiliated" by her fame-hungry boyfriend.
The 34-year-old star has accused her now ex-beau David McIntosh - who appeared as Tornado on the UK TV game show 'Gladiators' in 2008 - of "stabbing her in the back" after he alerted photographers of their whereabouts while the pair enjoyed a romantic holiday in the US.
A source told The Sun newspaper: "Kelly thinks David has been using her. She felt hurt and humiliated when she began to realize he was more interested in fame than he was in her.
"He was desperate to be in the papers and she kicked him out as soon as she realized that.
"She immediately deleted any evidence of them being together on her online profiles."
The busty brunette called time on their 45-day relationship earlier this week and has since been trying to get back in touch with her ex-boyfriend Thom Evans, 28 - whom she dated for two years until 2013 - but he's set to snub her as he's trying to rekindle his romance with his ex-girlfriend Jessica Lowndes.
The source explained: "She has attempted to speak to him [Thom] and meet up for dinner as they are both in the US.
"But he's trying to get back with Jessica Lowndes, the '90210' actress, and so is unlikely to meet Kelly."
Kelly and David, 27, struck up a romance last month after meeting each other at a New Year's Eve party at her bar, the Steam and Rye, in London.
It is believed the former Royal Marines commando is Kelly's first boyfriend since she ended her seven-month relationship with Danny Cipriani, whom she had been in an on/off relationship with since 2008, last August after he allegedly cheated on her.
