The I'm A Celebrity winner is entering the race for Christmas number one with the musical accompaniment to her current Iceland adverts.
All proceeds from Solomon's cover of Chris Rea's 1988 release will go to Alzheimer's Research UK and children's hospice charity Together For Short Lives.

Speaking to The Sun, Solomon confessed that she was nervous about going head-to-head with the winner of this year's series of The X Factor.
"If I got Christmas number one it would be the best feeling in the world," she said. "I'd be ecstatic. I don't know if I'd be able to look Simon Cowell in the eye! No, I don't think he'd talk to me!"
Solomon added that she is planning to release her debut album in February and claimed that she had been given more "freedom" by signing a record deal with someone other than Cowell.
"As much as it would have been lovely to have got signed straight away, where I've waited and not been in a contract with Simon or Syco, I've been able to do whatever I wanted," she said.
"Now I've got the freedom to choose what I want to do which is such a privilege. I've been writing a lot of it myself. It's acoustic songs that mean something to me."
Solomon released her first single - a cover of 'At Last' by Etta James - back in May 2010, but the song failed to chart.
She recently claimed that she will distance herself from reality shows and focus on her music career.
