Dating rumours involving Electra, 40 and Cowell, 53, started swirling since they were spotted hanging out and cozying up for pictures while on a dinner date last year, reported E! online.
"We're friends. I think he's on vacation right now. We've hung out a few times. He's an awesome person. And I absolutely adore him," she said.
Electra became close to Cowell after she split from ex-fiance Rob Patterson back in October around the same time she began hanging out with Cowell.
Electra and Patterson had been together for around five years before parting ways.
