Ever since Ashley Cole cheated on Cheryl Cole, we've been hoping that she would find someone who wouldn't hurt her again, and now that she has (in the form of Derek Hough), Simon Cowell has told the beauty to dump him.

According to the Mirror, Si thinks that Cheryl should stay single for the sake of her career.

And it doesn't look like Simon was joking when he told Derek what he thought recently.

A source revealed: “Derek and Simon were friendly enough, but just very firmly told him exactly what he thought.

“During the dinner Simon told Derek, 'It's nothing personal, I just don't think Cheryl should be spending so much time with you so soon after her marriage breakup'” to which Derek told the source: “I just could not thaw him out. He is just so firm about where he stands.”

“He went on to warn Derek of encouraging Cheryl to jump into a rebound relationship and said Cheryl should be concentrating on her career because the next few choices she makes are critical. Simon knows Ashley held Cheryl back.”

We wonder what Cheryl will do, because the source went onto reveal how much Cheryl values Simon's opinions.

“Derek told me Cheryl respects Simon more than anyone else and she knows it is down to him that she is where she is today. She thinks he is wise and emotionally intelligent, which is why Derek is so scared that Simon's opinion could hurt them in the long run.”

We know that Simon only has Cheryl's best interests at heart but c'mon she is a grown woman, we're sure she can make her own decisions.
