Meghan Markle's on screen husband Patrick J  Adams jets into the UK

Meghan Markle's Suits co-star Patrick J. Adams checks out his wedding suit as he jets into the UK for the Royal wedding.

Adams looked like he was feeling the love of the occasion as he held hands with his actress wife Troian Bellisario as they walked through Heathrow Airport.

Adams' character Mike Ross recently tied the knot with Meghan's character Rachel Zane in the hit US legal drama Suits.

The co-stars are very close off screen and the 36-year-old Canadian actor looked excited to be in the UK to watch his co-star do it for real at Windsor Castle tomorrow

A fellow passenger told MailOnline: 'Patrick was very excited about the wedding.

'He was talking on the phone and chatting about the marriage arrangements with his wife throughout the flight.

'The couple held hands throughout the flight and were clearly feeling the love.'

Mr Adams and Ms Bellisario sat in the first class cabin for the nine-and-a-half hour United Airlines flight from Los Angeles LAX Airport to Heathrow.

The couple both brought their wedding outfits in the cabin to ensure they look their best at the Windsor Castle ceremony tomorrow afternoon.

'Patrick was carrying his outfit in a suit bag and his wife had her dress in a special carrier too,' the onlooker said.

Dressed in a black leather jacket and black baseball cap Mr Adams and his wife, who wore a Burberry rain jacket, wide-brimmed hat and jeans, were met by friends at they collected their luggage and whisked them out of Heathrow yesterday. 

Mr Adams and Ms Bellisario got straight into the party spirit, enjoying a 'traditional ale' at the Royal Standard of England pub, a few miles from the wedding venue in Windsor.

He first teased fans of his arrival as he posted a photo of The Royal Standard of England in Buckinghamshire which was captioned: 'I have historically ale'd.'

He then later added a photo outside the historic pub while clad in a black leather jacket, chinos and T-shirt.

Patrick also stood alongside his other half Troian, who is known for role as Spencer Hastings in Pretty Little Liars, and a fan, who he wished a Happy 18th Birthday to, in the snap.    

The actor's arrival in the UK comes as a number of his and Meghan's Suits castmates Patrick jetted into the country. 

Gabriel Macht and Rick Hoffman, who shoot their series in Toronto, each took to their Instagram accounts this week to share images of themselves both enjoying the English capital and hinting of travel to the UK ahead of the big Berkshire bash. 

On Wednesday afternoon, 46-year-old Gabriel, who plays formidable star Harvey Specter on the show, uploaded a romantic snapshot of himself nuzzling his wife smiling Jacinda Barrett as they relaxed by the water in Hyde Park.

'Yesterday #london #hydepark Today #guess,' he captioned the picture, which garnered more than 100,000 likes in three hours and attracted a stream of comments from fans, who all but guessed that he was in town for the wedding.

The actor's wife of 14 years also shared some images of her own from their leisurely excursion at the central London park - which is just a stone's throw away from Megan and Harry's residence at Kensington Palace.

'Hanging in Hyde Park. Loving our time in #london,' the 45-year-old Australian-born actress wrote beside an image of her and Gabriel hugging as they donned matching sunglasses while gazing out at the scenic views.

And in showing that they're getting acquainted with all things regal, Jacinda also uploaded an adorable snap of herself sharing a kiss with her four-year-old son Luca in front of the most well-known Royal residence of them all, Buckingham Palace.

Also presumably having crossed the Atlantic, Rick Hoffman, who plays the highly strung cat lover Louis Litt on Suits, took to Instagram in the early hours of Wednesday morning to share a video as he prepared to travel 'east'.

The 47-year-old actor told fans in the brief clip: 'Just checking in with you, just finishing up my portion of episode 804 and then heading east for some special event and I'm very excited about that.' 

Sarah, 45, played Donna Paulsen alongside Meghan in the hit legal drama and has appeared in numerous TV series including Law & Order and Six Feet Under.

The bride is no doubt delighted by the arrival of her friend who she previously described as 'not just my Suits sister wife, but my sister'. 

Wendell Pierce, who plays her father Robert Zane, has so far stayed mum about any possible travel plans on Twitter.

Dulé Hill, who joined the cast as lawyer Alex Williams last year, also hasn't mentioned the wedding on his social media accounts, though he has just returned from his own honeymoon in the Maldives after tying the knot with Psych co-star Jazmyn Simon.
