Playboy empire founder Hugh Hefner was known for his love of much younger women prior to his death at 91.

And now the media mogul’s widow, Crystal Hefner, 37, has thrown shade on Hollywood superstar Leonardo DiCaprio by calling him the ‘new Hef’.

DiCaprio, who turns 50 this year, is currently dating 25-year-old Italian model Vittoria Ceretti, following a string of romances with women of a similar age.

Crystal, 37, who married to Hefner for five years until his death at 91 in 2017, made the bombshell comment on the Hit Network Carrie and Tommy podcast on Wednesday.

‘Leo DiCaprio is turning into the new Hef,’ Crystal said.

She also divulged bombshell details of The Departed star’s time at Hefner’s mansion.

Crystal claimed Leo ‘hooked up’ with Rihanna, 36, at a Playboy mansion party, when the singer was still in her 20s.

‘I remember Leonardo DiCaprio and Rihanna hooking up one night,’ said Crystal. ‘I remember thinking, “That’s smart, hook up with each other and then we won’t tell anyone.”‘

Divulging details about other A-listers she saw regularly at the mansion, Crystal said, ‘I remember Jack Nicholson would come there a lot. Random celebrities like Pauly Shore, Corey Feldman [too].’

‘Others came once in a while just to check it out – Justin Bieber, Kylie Jenner. They just came by to check it out, and I understand their curiosity.’

The former model and Playboy ‘Playmate’ also was asked about her relationship with Hefner, which she described as ‘possessive’.
