The blonde and her ex Lucas, the son of art dealer David Zwirner, got engaged back in January after a year of dating, but Page Six recently revealed they ended their relationship.
The report claims that it was the thespian who broke it off with the editor, though no reason for the separation was given.
Representatives for both Miller and Zwirner did not respond to requests for comment from MailOnline at the time.
Sienna was previously engaged to actors Jude Law, 47, in 2004 and Tom Sturridge, 34, the father of her daughter Marlowe, eight, in 2012.

In a 2017 interview with Harper’s Bazaar, Sienna spoke about maintaining a friendship with her ex, saying of Tom, who is now reportedly dating actress Maya Hawke: ‘We still love each other.’
‘I think in a break-up somebody has to be a little bit cruel in order for it to be traditional, but it’s not been acrimonious in a way where you would choose to not be around that person.’
‘We don’t live together, as has been reported recently, but we do half the time,’ she added. ‘Everybody will stay over or we’ll all go on holiday and that’s because we genuinely want to be around each other.’
‘It’s great for our daughter that she has two parents who love each other and are friends. He’s definitely my best friend in the entire world.’
