Kaya Scodelario and Benjamin Walker look to have got engaged, after the 22-year-old actress posted an image of an engagement ring on Instagram and gushed about her hunky man.

The 22-year-old actress has sparked rumours the 'Abraham Lincoln: Vampire Hunter' actor has popped the question by branding a ring on her finger and gushing about her love for the hunk.

Alongside an image of the couple kissing on Instagram, she wrote: "@findthewalker thank you for making me the happiest woman in the world. (sic)"

The photograph of the embracing couple was posted just minutes after another image of her posing with her mother and the 32-year-old actor, in which she showed off an engagement ring and hinted she'd moved in with the star in New York.

She wrote: "Showing mum around our new home I [heart] NY@findthewalker (sic)."

The 'Maze Runner' actress revealed earlier this year she was finding the relationship tough because of the distance between them.

She said at the time: "Ben lives in New York and I live in London, so we have to work hard to see each other. You have to go for it, which I like."

The surprise announcement comes just 19 months after the actor split from the daughter of actress Meryl Streep, Mamie Gummer, who he wed in 2011, and only months after he and Kaya began dating after meeting on the set of fantasy film 'The Moon and the Sun'.
