Man in black Josh Brolin shares a smooch with his leggy fiancée Kathryn Boyd at Los Angeles premiere of Everest

Josh Brolin must be clearly gaga for his fiancée Kathryn Boyd.

The 47-year-old Hollywood tough guy seemed to melt in the presence of the 28-year-old stunner as they attended the Los Angeles premiere of his new film Everest on Wednesday.

Josh's lady love was dressed in a stunning black mini-dress that showed off her long, toned limbs and featured one billowy sleeve.

The seasoned actor didn't mind if heads turned Kathryn's way but then again she was also outfitted in black strappy high heels that gave her an added edge.

Kathryn, a graduate of the University of Georgia, wore her long blonde hair straight and sleek without a strand out of place.

The pair stopped to share a kiss on the red carpet at the event. 

Josh, meanwhile, went dark all the way, choosing a black suit, black dress shirt and black tie along with polished black shoes.

'I'm the guy who has to force himself to back off,' Josh told E! News. 'I'm such a control freak and I want to control everything. It's not even that I want to control it - I just want to be in the middle of it.

'I want to be in the nucleus of it because that's the fun part. That's the nectar.'

He added: 'We're still in the midst of figuring out the best time and all that stuff, but it's very exciting.'
