The 32-year-old claimed that she has never been alone with the former England captain, following reports that the ex-Manchester United star had cheated on his wife Victoria Beckham with Jenkins.
Jenkins tweeted: "Dear Twitter friends, I've read some horrible rumours on here & want u 2 know I absolutely deny I've had an affair with David Beckham.
"The rumours are very hurtful, untrue & my lawyers tell me actionable. I've only met David twice: once at the Military Awards in 2010 & on a night out in the West End in Feb 2012.
"We were out in a group of friends & it was just a normal fun evening out. Just so we are clear I have never been on my own with him and never arranged to meet up."
The rumours regarding Beckham's alleged infidelity began circulating on Twitter today.
