They've been inseparable ever since they embarked on their romance back in 2014.

And Lily James, 28, and Matt Smith, 34, showed that they're still very much in sync on Friday, when they were spotted going for a bicycle ride together around the coastline of picturesque Croatian island Vis.

Lily, who is currently shooting her lead role in Mamma Mia: Here We Go Again! in Croatia, was seen leading the way for much of the time as the pair pedalled on their individual cycles while taking in all of the breathtaking scenery.

This is how we roll: Lily James and her boyfriend Matt Smith were spotted enjoying a bicycle ride on the Croatian island of Vis on Friday

The former Downton Abbey star wore a plunging black minidress teamed with grey New Balance trainers for her leisurely excursion.

Shielding her eyes with a pair of stylish sunglasses, she tied her golden tresses back with a purple bandanna before throwing on a protective helmet for their long ride.

Matt was also seen looking casually cool, wearing a sleeveless grey top with black shorts and matching trainers, while shades and a helmet kept him protected.

And Lily appeared keen to make the most of the Mediterranean sunshine, as later that day she shared an Instagram post of herself relaxing in a tiny striped bikini. 

She captioned the scintillating snapshot: 'Day off, don't block my sun.'

Despite their busy acting careers, it seems Lily and Matt's romance is going from strength to strength, with the actress recently hinting that it could only be a matter of time before her boyfriend pops the question.

Lily playfully dropped hints that engagement could be on the cards when she tried on a number of diamond rings at a De Beers event, held at prestigious London department store Harrods, earlier this year.

The English rose brought her boyfriend's sister along, cabaret dancer Laura Jayne, 37, to make sure Matt knew what ring she has her eyes on.

Introducing Laura, she said: ‘I’m dating her brother, and hopefully she will soon be my sister-in-law.'

Although she was more than happy to try a 71-carat yellow oval-cut diamond solitaire, it would cost a pretty penny at £7million.

The Cinderella star, however, proved more modest in taste as she cherry picked the 9.1 carat diamond Aella ring at a cost of £200,000 as her fairytale choice.

Lily told The Daily Mail's Sebastian Shakespeare: ‘This is the diamond that has found its way to my finger. It’s very unique. I would definitely want something like this.’ 

Filming kicked off for the prequel to 2008's Mamma Mia in mid-August, with the hotly-anticipated film slated to be released next July.

The upcoming flick 'goes back and forth in time to show how relationships forged in the past resonate in the present', according to Deadline.

Lily will play Donna way before she became Mamma Mia! heroine Sophie's mother or the owner of the Villa Donna from the first film.

I thee wed? Earlier this year, Lily hinted that she was hoping Matt would one day propose

Seasoned actors Pierce Brosnan, 64, and Meryl Streep, 68, are expected to reprise their roles in the sequel, and pick up where viewers left off.

The original movie was set on a Greek island where young bride-to-be Sophie, played by Amanda Seyfried, discovered that any one of three men - Bill (Stellan Skarsgard), Sam (Pierce) or Harry (Colin Firth) could be her father.  

The original was based on the smash hits of Swedish rock band ABBA, formed in Stockholm in 1972.

Although the storyline remains a secret, it is believed that a number of ABBA hits that weren’t included in the first film – such as Waterloo and Knowing Me, Knowing You - will be featured.
