Hannah previously dated Italian businessman Gianluca Cugnetto.
The pair had been together for more than a decade and were even rumoured to be engaged before their split.
Hannah previously said she is 'too busy and picky' to start dating again - though said if she was to ever date again she would have a strict criteria.
She told Michelle Visage on the Rule Breakers podcast: 'I'm a pretty picky girl really and have such a very specific kind of criteria of things.
'One of the main things with guys, just come on man, positivity - positivity and charisma and I'm your gal. But there's an awful lot of misogs (miserable old gits) out there. I don't need it.'
She added: 'I don't go much on stereotypical cutey pie, whatever, sexy, whatever.
