The pair met while playing lovers in the forthcoming fantasy film The Man Who Killed Hitler And Then The Bigfoot.
And Aidan Turner couldn’t take his hands off his girlfriend Caitlin FitzGerald as they walked her beloved dog, Charlie in London.
The Poldark star, 35, packed on the PDA with the American actress, also 35, planting a kiss on her lips as they strolled through a park on their romantic day date.

The couple, who have been dating since February, looked in the throes of love on their stroll, with Aidan later scooping up Caitlin’s tired Norfolk Terrier in his arms as they headed to a fish and chip shop.
The hunky actor looked worlds away from his Poldark attire as he sported a simple white t-shirt and stripy shorts for their outing.
Aidan could hardly wipe the smile from his face as they strolled through the streets of the capital, with him regularly showering Caitlin in displays of affection while little Charlie walked alongside them.

Meanwhile, Gossip Girl star Caitlin, who cancelled a series of acting masterclasses back home in Maine before heading to see Aidan, cut a casual figure in a pin-striped shirt and ripped denim shorts, which made the most of her leggy frame.
She teamed the look with black sandals, tortoise shell sunglasses and a calico bag.
The pair met while playing lovers in the forthcoming fantasy film The Man Who Killed Hitler And Then The Bigfoot, which opens in the US this month.

It is thought they became close while filming scenes in Massachusetts. Sources say they rarely mingled with other cast members while staying at the historic Deerfield Inn, near Boston.
In the film, Turner plays an American soldier in the Second World War who leaves Caitlin’s character behind to embark on a dangerous mission to assassinate Adolf Hitler – and he is later called upon to kill a mythical sasquatch in the Canadian Rockies.
Turner split with artist Nettie Wakefield, 30, last June. Before that he was in five-year relationship with fellow actress Sarah Greene, 32. They separated in 2015. Caitlin meanwhile has dated Welsh actor Michael Sheen.

In an interview last month, Turner, currently appearing in the fourth series of Poldark, coyly hinted at finding new love, saying: ‘I do have a girlfriend, yeah.’
Last month Glamour magazine published an essay by Caitlin entitled ‘No one can tell you what good sex looks like’, in which she admitted having ‘had some really bad sex in my life’.
She said she had initially ‘crafted my bedroom behaviour around what I had seen women do on television – lots of excessive moaning and hair tossing but very little personal satisfaction’.
Asides from his Poldark and filming duties, Aidan has been busy treading the boards in the West End show, The Lieutenant.
The hunky actor plays Padraic, a young, unhinged terrorist who returns home and goes on a murderous rampage when he discovers his cat, who he refers to as his ‘best friend in the whole world’, has been killed.
In true Martin McDonagh style, everything descends into chaos as Padraic storms back into his father Donny’s (Denis Conway) home, and tries to exact his revenge but is then interrupted when fellow terrorists turn up on his doorstep.
The piece, set in 1993 on the island of Inishmore, County Galway, was first performed by the Royal Shakespeare Company in 2001 and was created by Three Billboards Outside Ebbing, Missouri director Martin McDonagh.
‘I think people will be surprised,’ the actor told the Daily Mail last year, while on a short break from filming the fourth — and penultimate — series of the top-rated BBC television Sunday night drama Poldark.
‘It’s the furthest I can get from Ross Poldark that I can possibly imagine.’
