Ulrika Jonsson has said that Leonardo DiCaprio "gives her the creeps" as she slammed his latest rumoured romance.
Leonardo has recently been pictured with 19-year-old model Eden Polani, with some thinking they are an item.
However, Ulrika has said that she disapproves of the the 48-year-old dating a teenager.
She has said that the reported relationship between the two is "sickening", saying it "gives me the creeps".
Leonardo, who has a reputation for dating younger women, raised eyebrows seen posing with Eden at a Los Angeles party recently but has since denied any reports of a romance.
Top 20 excuses Brits use to cancel a date - from sickness to work emergencySome have noticed that Eden would not have been born when Leo's hit film Titanic was released back in 1998 - 25 years ago.
Speaking in her The Sun column, Ulrika, 55, said that she wouldn't want to date someone that young.
Ulrika wrote: "I know I’m not the only one who finds Leonardo DiCaprio’s pursuit of much younger women not just distasteful but also sickening.
"While I understand the glitz and glamour of a Hollywood star must be irresistible, it’s unfathomable that someone so young could consider spending her formative adult years with a man who is old enough to be her father.
"The idea that I might date or, God forbid, be in a relationship with an 18 to 19-year-old man does not only feel wrong and counterintuitive, but just a step too far. I’m afraid it gives me the creeps."
Fans have recently come up with the theory that Leonardo only dates women up to the age of 25.
Leo split with his latest girlfriend Camila Morrone in August 2022 just weeks after she turned 25.
The pair had been together for four years.
However, it seems the theory was questioned when it was rumoured that Leonardo got close to model Gigi Hadid at a party in New York City in September.
If rumours that they were dating were true, it would be the first time the actor dated a woman older that 25 who is also a mother.
