Who is Sarah Harding’s ex-boyfriend Aaron Lacey? Celebrity Big Brother winner’s secret lover she left for Chad Johnson

SARAH Harding shocked fans when she snogged Chad Johnson in the Celebrity Big Brother house, while revealing she had a boyfriend on the outside.
But what do we know about her man - who is he, how long have they been dating, and has he reacted to her tryst with Chad? Here's the lowdown...
Who is Sarah Harding's boyfriend Aaron Lacey?
Sarah ruled out all possibility of romance before entering the Celebrity Big Brother house, claiming she had thought about having kids with her latest beau.
She told The Sun's Dan Wootton: "I'm spoken for so I won’t be flirting with anyone in the house.
"I'll miss him and my three dogs the most. I would love to be a mum one day, that would be nice chapter to add to my life."
Since entering the house the Girls Aloud singer confirmed she had been seeing someone on the outside, but did not reveal the identity of her mystery man in interviews or on Celebrity Big Brother.
However, following her very public cheating with US reality star Chad Johnson, The Sun revealed Sarah's secret boyfriend is Aaron Lacey, a plasterer from High Wycombe, Bucks.
A pal of the 33-year-old said: "He’s heartbroken. He fell for her.
"They were inseparable. He supported her going on Celebrity Big Brother and watched nightly.
"He’s devastated she went behind his back."
Another source said: "They met in a bar and things blossomed very quickly.
"They were starting to get close. He lived at home before but then moved in with her."
However, following the events in the CBB house, Aaron is now back living with his parents.
What happened between Sarah and Chad Johnson?
Sarah may have been thinking about love, marriage and babies with her boyfriend before meeting Chad Johnson.
However that quickly got sidetracked as she has spent much of her time on CBB developing a romance with the US reality star.
Sarah infuriated viewers when she first kissed Chad, locking lips in the bedroom after an eviction before having another cheeky kiss in the kitchen.
Chad told Big Brother: "I like hanging out with Sarah. We flirt. I just want to keep hanging out with her, and see what happens."
And it looked like things were moving fast between the pair as they grew closer and Sarah seemed to forget any romance waiting for her outside the house.
However she has denied having sex with the lothario after they were spotted getting frisky under the sheets as they shared a bed.
Viewers were shocked when the singer performed a sex act on Chad on top of the covers.
Meanwhile former housemate Trisha Paytas has claimed the romance is "fake", and just being played out for the cameras.
Did Sarah mention her boyfriend to Chad?
Sarah has admitted she feels "terrible" about snogging Chad Johnson on Celebrity Big Brother during a heart-to-heart with the hunky American.
She said: "We got busted big time. At the end of the day we care about each other, we're like best friends in the house.
"Right now I really just want to draw a line under it, because people were egging it on."
Sarah told Chad they would need to take their foot off the pedals when it came to their romance as she had someone on the outside and did not want to hurt them.
She added: "I just don’t want to make a fool out of anybody."
Chad agreed: "I don't want to be an a**holeto the guy back home, that's not good," but he's hinted he would still like to take his romance with Sarah further.
