Earlier this month, Casey appeared on , where she revealed that she has never had a boyfriend. 

Host Dave Hughes started by going through her resume, with the songstress having won Idol and her season of I‘m A Celebrity… Get Me Out Of Here.   

Dave asked: ‘what possibly could be your problem?‘

Appearing shy, Casey replied: ‘So, look, slight problem…I‘m almost 30 and I‘ve never had a boyfriend.‘

The singer admitted she‘s had a couple of ‘toot and boot‘ relationships.

‘Not a full-time, like, come home, made dinner, like…[sort of thing],‘ she said. 

After joking about the possibility of getting a third cat, the songstress said she just wants ‘someone that‘s not a f**kin‘ tool.‘ 

In the segment, Casey revealed she has tried to meet men on dating app Tinder and at pubs, even confessing to trying premium dating service, e-Harmony.         

‘Yeah, look, I‘ve paid for it, I‘ve done eHarmony,‘ she said. 

Host Dave, then took things into his own hands, getting the songstress back to Tinder – Casey receiving 45 ‘matches‘ in 12 hours.      

In the past, Casey was involved in a high-profile catfishing scandal, which saw her best friend pose as her online lover.
