Elizabeth Olsen and Boyd Holbrook split?

Elizabeth Olsen has reportedly split from her fiancé Boyd Holbrook.

The couple - who have been together for more than three years - are said to have called off their engagement after the 25-year-old star was spotted without her engagement ring on the weekend, a source confirmed to Us Weekly magazine.

Boyd - who is a model, actor and artist - was also seen appearing to confirm his single status while flirting with a mystery blonde woman at CAA's Pre-Golden Globes party at West Hollywood's Soho house earlier this month.

The 33-year-old star first began dating the 'Godzilla' actress in 2012 after they met on the set of their film 'Very Good Girls' - which also starred Dakota Fanning and Demi Moore.

The couple then got engaged last March - just two weeks after it was revealed Mary-Kate was planning to marry financier Oliver Sarkozy.

A source said at the time: "They've been by each other for a while, taking a lot of couple time."

An insider added of their engagement: "They moved into a place in Brooklyn a few months ago."

Elizabeth confessed previously that she was in no rush to get married and wanted to take the time to plan her perfect wedding.

She said: "I'm relaxed about it, but I am excited and planning ideas because it's fun - it's just like throwing a party to celebrate life. I love being in a relationship a lot."

The blonde beauty also admitted she was thinking about having children with her then-fiance.

She said at the time: "My mother would love it if I was in LA with kids. I loved growing up in LA, but I always think about places I've never been to before, like Oregon."
