Olly, 31, is said to be getting close to fellow pop star Diana Vickers – and apparently there’s always been a spark between the two former X Factor contestants.
A source told The Sun: “They’ve always had a soft spot for each other. Now since they are both single they have been in touch.
“There’s an obvious attraction between the pair of them and they’re both young and good-looking.
“They’re just fooling around at the moment and having a laugh with each other. Neither wants anything serious as they have both just come out of long-term relationships.”
Diana, 24, recently split from boyfriend George Craig after four years.
Olly previously admitted that their management team had to keep them apart because they were worried they’d distract each other from work.
Speaking in 2010, the X Factor host said: “We get on really well but management want to keep us apart – they don’t really want us talking too much because we have our own promotion to do.”
During an appearance on ITV’s Loose Women earlier this month, Olly suggested model Francesca struggled to cope with his devoted female fans.
