Singleton is said to have split from Dennis (pictured in 2019 with his former partner, 2GB radio host Steve Price) over concerns over their nearly 40-year age gap
Singleton reportedly ended the relationship due to concerns over their nearly 40-year age difference. They had been together for about 18 months.
Dennis – a divorced mother of two from western Sydney – worked for ‘Singo’ on his Macquarie Radio Network 2GB station and knew him for several years before they started dating.
However, his position was terminated by 2GB’s new owner, Nine.
She has since started a new job at an American skincare company.
Sources close to the former couple told the Telegraph that Dennis was “blindsided” by the split and was busy planning his future overseas vacation.
They also said Singleton “probably would have been generous with Dennis” after their sudden split.

Dennis is also said to have hoped for a proposal from Singleton which would see her become his seventh wife.
She once dated 2GB radio host Steve Price with the couple pictured together in October 2019.
Price had separated from his second wife Wendy Black the same year, but denied the breakup in June.
Singleton also has an impressive list of ex-girlfriends and wives – having been divorced six times, including once to 60 Minutes reporter Liz Hayes in the early 1990s.
Before Dennis, Singleton dated New York-based PR expert Venessa Merrin, as reported by Daily Mail Australia.
Their relationship began in 2016 and reportedly only ended once Singleton went official with Dennis in 2021.
Singleton made his fortune in the advertising business in the 1970s and 1980s.
