Elle Macpherson has sparked rumours she is dating Olivier Sarkozy - the brother of ex-French President Nicolas.
Last year, Elle, 57, confirmed her split from disgraced British medic and anti-vaxxer Andrew Wakefield.
Olivier, 52, divorced former US child star Mary-Kate Olsen early last year.
He and Elle looked cosy as they shared a joke at an Elton John gig in New York Last week.
An onlooker said: “They seemed really happy together, it looked like they could be a new item.”
Model Elle split from billionaire ex-husband Jeffrey Soffer after four years in 2017.
The Aussie was previously married to French snapper Gilles Bensimon.
She has two children with another ex, French financier Arpad Busson.
In December, a spokesman for Elle confirmed “unequivocally” that her relationship with Wakefield “terminated almost two years ago”.
The ex-doctor from Berkshire was struck off in 2010 after his claims of a link between MMR jabs and autism was exposed as an “elaborate fraud”.
Olivier wed Mary-Kate in 2015 but the couple broke up five years later.
In divorce papers, Mary-Kate, 35, said Olivier moved ex-wife Charlotte Bernard and their two kids into their New York home, along with his mum, meaning she could not stay there.
