The 'Fight For This Love' singer intends to support her fellow Girls Aloud bandmate following her alleged "terrible fight" with boyfriend Theo de Vries, says the Daily Star.
A source claimed: "Cheryl knows all about heartache and hard times after Ashley cheated on her. She has been in touch with Sarah and is really worried about her.
"Sarah has been in pieces and crying. So Cheryl thinks a girls' holiday in the sun would do her the world of good. She is desperate for her to chill out."
Harding and de Vries are both apparently facing assault charges over the incident that occurred on New Year's Eve.
Yesterday, de Fries told a newspaper that a bite mark and bruised eye were caused by Harding during the physical altercation.
