"Mr Holmes" - UK Premiere - Red Carpet ArrivalsActors and BFFs Ian McKellen and Patrick Stewart aren't shy about showing their affection for one another, whether it's McKellen officiating Stewart's wedding or the pair bro-ing about town in matching bowler hats. But the pair took things to the next level during the recent premiere of McKellen's latest film, "Mr. Holmes."

On Wednesday, Stewart attended the London premiere of the flick to support his longtime pal, and ended up performing some serious PDA with his fellow actor. The twosome embraced on the red carpet (which was really a cobblestone walkway), and then locked lips, delighting Stewart's wife, Sunny Ozell, as well as McKellen's costars and the fans and media that gathered for the event.

It's heartwarming to see two men share their platonic love for one another so openly (even if that love is sometimes misconstrued), and it's even better when it's two gentlemen as delightful as McKellen and Stewart. Cheers to the "X-Men" costars, and here's to many more years of their awesome bromance.
