Josh Hartnett and Tamsin Egerton go low-key as they step out in matching sunglasses to pick up healthy snacks in Hollywood

They say the couple who eats well together, stays together.

And it certainly seems that healthy living suits Josh Hartnett and Tamsin Egerton, who are looking more loved-up than ever, and rather similar, too.

The good-looking twosome stepped out in West Hollywood on a health food mission on Monday to grab some healthy snacks from a nearby health food and vitamins store.

The Hollywood hunk, 36, led the way, looking casual in a navy shirt and black jeans, covering his face in a pair of retro sunglasses.

And his British girlfriend followed behind, relaxed in a flattering pair of denim cut-offs and a black t-shirt, her outfit markedly resembling his, all dark colours and shades.

The 26-year-old blonde beauty kept her locks natural and curly, and appeared to be going make-up free under her oversized, funky sunglasses.

As they made their way across the car park of the Lassens Natural Foods & Vitamins store, they popped all their goodies into the boot of their car before heading off for the rest of their day.

Low-key couple: The twosome - who have been together for over two years - were completely relaxed in each other's company

A low-key couple, they are rarely seen out and about together, but they have been in a steady relationship for over two years.

The couple first met when they starred opposite each other in 2012's Singularity, though it's believed their romance didn't begin until a year later. 

And the St. Trinians actress is loving her life with her handsome man, who rose to fame in the late 1990s in teen movies such as The Faculty and The Virgin Suicides. 

'Yes, my love life is great,' Tamsin told MailOnline of her relationship with the actor, although she made it perfectly clear she's not ready for family life.

'Not yet... I'm 25!' she said. 'I want to stay travelling and working as much as possible.' 

She also spoke about how the devoted man moved to Dublin to spend time with her while she was filming her move Love, Rosie last year.

'We were filming in Dublin and Dún Laoghaire so we would all go to dinners together and we all stayed in the same hotel so that was always quite fun,' she said of the bonding between Josh and her castmates Lily Collins, Sam Claflin, Suki Waterhouse and Jamie Winstone.

'We'd go for walks round Dublin, go to pubs have a little drink together, there was one night at Lillie's Bordello which is a club in Dublin that is quite infamous. 

'It was young people together just having a laugh and getting on.' 

Josh often spends time Dublin himself to film his role in TV drama Penny Dreadful.
