Sarah Harding reportedly had a fling with Ed Sheeran’s rapper cousin.
The former Girls Aloud star is said to have enjoyed a brief romance with Ed’s cousin Jethro Sheeran after the pair started working together on new music.
A friend of the pair revealed: "Sarah and Jethro had been working together on new music for her and they got on really well.
"They were partying one night a few months ago and ended up back at her hotel room, where things got out of hand."
However, their brief romance quickly subsided and the duo remain on good terms.
The source told The Sun newspaper: "There was a bit of a fling but they both soon regretted it and then fell out – Jethro can be hot-headed and said some things he regretted.
"But they made up recently and are still on good terms now."
Sarah – who is currently single, having previously dated the likes of Tom Crane and Mark Foster – praised Jethro as she tried to relaunch her pop career in 2015.
The blonde beauty said: "Jethro’s a really talented producer and it’s been great to spend a bit of time with him in the studio as well."
Jethro has also written about the 35-year-old star on Twitter, making reference to her time appearing in ‘Ghost – The Musical’.
He previously wrote on the micro-blogging site: "Looking forward to seeing Sarah Sozzle Harding Harding as the lead in Ghost in Bristol Monday then catch up at Turtle bay Turtle Bay after for dinner and cocktails and catch up and talk our awesome new Single! Good times! Boom! xx (sic)"
Despite this, a source close to Sarah has insisted the duo have never been anything more than friends.
The insider said: "The relationship is purely business. They are friends."
