The Game Of Thrones actor, 30, joined co-stars Liv Tyler and Edward Holcroft at the event, supposedly now betrothed to his Scottish girlfriend of five years Rose Leslie - who he met on the HBO series in 2012.

Kit was giving nothing away as he posed with his fellow actors, in a pale blue shirt, skinny navy jeans and brown leather brogues, his hands firmly kept in his pockets.

He shot his trademark smoulder down the lens of the cameras, a slight grin on his lips. 

Liv poured her curves into a velvet black floor-length gown, with a semi-sheer detailing on the top half.

The 40-year-old daughter of rocker Steve Tyler wore her raven tresses trickling down one shoulder and highlighted her pout with bright red lipstick.

Edward, 30, wore an open collar whit shirt, a black blazer and slacks, mirroring Kit with an equally Blue Steely glare.

Gunpowder will air on Saturday nights over the autumn on the BBC and is based on the Gunpowder Plot in London in 1605 with Kit as the lead role Robert Catesby, a distant relative of King James VI & I.

Kit and Rose, who shut down engagement speculation over the summer, are rumoured to have told friends and family last week that they're set to wed.

'They're yet to set a date, but told friends and family last week that they've got engaged,' a source told The Sun.

'Kit's known for ages he's wanted to marry Rose but he wanted them to get a house and settle down a bit first.'

The insider claimed Kit felt marriage was the natural next step for him and Rose, also 30, after they moved into a £1.75million mansion in East Anglia.

'After moving in together in January he felt it was the right time to take the next step,' they said.  MailOnline have contacted reps for Kit and Rose for comment.

'That you haven't just moved into mine. Move anything you want around, change anything, chuck anything out".'

The stars shut down reports that they are to wed, after Life & Style claimed the pair were 'planning their nuptials'.

The U.S. tabloid alleged that Kit had popped the question over a romantic dinner, leaving his long-time girlfriend in tears.

'Kit recently cooked Rose a romantic candlelight dinner and proposed to her. She burst into tears and immediately said yes!' a unnamed source claimed.

However, the stars' reps denied that the pair were set to tie the knot at the time.

Rose, who found fame as servant girl Gwen in Downton Abbey, is said to want a traditional wedding 'with kilts and bagpipes' in her native Scotland, Life & Style reported.  

At the season seven premiere for Game Of Thrones in Los Angeles, Kit spoke about his relationship with his former co-star.

'I think that's the really special thing about it is that we met on this show and here we are seven years down the line back here promoting season seven,' he said on the red carpet.

'I mean it's mad. It's such a special thing. I'm so privileged,' he added.

While the actor didn't divulge too many details about their relationship, which had apparently been on and off since 2012, he said the couple were 'very, very happy.' 

He also revealed last year how 'easy' it was to fall in love with Aberdeen beauty Rose. 

Recalling his favourite memory of shooting GoT, he told L'Uomo Vogue: 'The three weeks in Iceland where we shot the second season... because the country is beautiful, the light of the North magic, and why it was there that I fell in love.

'If you are attracted to a person and in fiction is your love interest, it becomes easy to fall in love.'
