Longtime partners Samantha Ronson and Cassandra Grey have ended their relationship, sources tell Page Six. “They finally broke up. They’ve had break ups before, but they finally broke up within the last few weeks,” a source told Page Six.

We first reported that Ronson and the beauty mogul widow of Paramount titan Brad Grey were an item in 2018 , about nine months after his death from lung cancer at 59. They have since been living in New York and co-parenting Cassandra’s son Jules. We hear the pair were even engaged at one point.

But according to a second source “Cassandra called off the wedding.” The pair — who are no longer living together — put their glamorous Tribeca pad on the market for $12 million in 2023. They are now renting it out.

“The relationship is definitely broken,” the first source said. Ronson — who is widely known as a celebrity DJ — is also a songwriter and makes up half of the band SpnR. She made countless headlines in the late 2000s for her toxic relationship with Lindsay Lohan.

She also comes from a famous entertainment family that includes her Grammy and Oscar-winning music producer brother, Mark Ronson (who is married to Meryl Streep’s daughter, Grace Gummer), fashion designer twin Charlotte Ronson, “Succession” actress sister Annabelle Dexter-Jones (whom we recently reported is dating famed chef Daniel Humm), and a less-famous musician brother, Alexander Dexter-Jones. And to top that off, her jeweler mom, Ann Dexter-Jones.
