The pair had been dating since March 2017, but Susie has revealed to Daily Mail that she had parted ways with the comedian.
'Mick and I broke up in September last year,' she told the outlet.
Her statement comes after she posted an Instagram picture of herself cuddling up to a suited man at Royal Randwick over the weekend, alongside the caption: 'My bookie...great tips!'
Before long, fans had begun asking what happened to her boyfriend.
'Where's Mick Molloy?' asked one follower. Another commented: 'What happened to Mick Molloy?'
Molloy is yet to comment on the breakup.
