The pair, who are currently working on the X Factor tour together, allegedly came clean about their romance after rumours began spreading.
According to The Daily Star, Cher told pals: “Aiden is my perfect guy. I’d get married to him.
“He and I are two very different people but he is so quirky.
“He makes me laugh all the time and my dad loves him.”
A source told the paper: “Every time Cher and Aiden are seen together backstage, all the singers are joking to her: ‘Got your big fat wedding dress yet?’
“We’re all expecting a big Disney-style cake too and lots of spray tan.”
Cher, usually quick to respond to tabloid tales on her Twitter feed, has yet to comment on the latest rumour.
