They've been doing the cute thing for years.
It's just really nice to see!
Yesterday, they walked the red carpet of the UK premiere of Star Trek: Picard and were, even for them, uncharacteristically cute. Like, next level.
Sir Patrick Stewart fixed Sir Ian McKellen's scarf.
"Jolly ole' day, pip pip hooray," he probably said.
Then, in a completely random move, they kissed.
They put on a full-on show for us.
Again, it was just really nice to see!
