The Girls Aloud singer -who was devastated by revelations the soccer star bedded a string of women days before they were thought to have reconciled in July - has finally decided to "cleanse" herself of her former spouse and is now ready to move on and find love again.
According to Britain`s Sunday Mirror, Cheryl told pals: "I`ll never go back. I don`t need him anymore.
"It took me this time to come to this conclusion and move on."
A friend added: "Cheryl finally made the decision that it`s all over. She felt mentally drained from everything he put her through and she partly blames herself for letting him back into her life.
"She`s completely cut herself off from him to cleanse herself of him, including deleting his number from her phone."
The news will come as huge relief to friends and fans of the `Parachute` hitmaker after she was spotted in a clinch with the soccer star at her birthday party in July.
The friend added: "What happened on the night of her party was a blip. Since then she`s taken time out again from him and now believes she was wrong. She can`t go back and try and right the wrongs of their marriage.
"What`s done is done and she`s got her head straight and believes it`s time for a new Cheryl."
Cheryl has reportedly even agreed to go on a date with a self-made millionaire who has been desperate to meet her.
The pal said: "One of the producers she`s been working with has a pal who`s desperate to meet her. He`s not in the public eye and is a self-made millionaire who is a very desirable bachelor. After splitting with Ashley she agreed to go on a date with him when she returns to Los Angeles."
