THE KISS IS 100% REAL.
This happened this over the summer at JibCon 2014. Jensen was looking a bit agitated during his panel and one of the convention organizers was wise enough to go get Misha and bring him on stage.
Misha immediately walked over and gently kissed Jensen on the cheek, instantly diffusing the tension.
Jensen spent the rest of the convention looking very happy, energetic, and upbeat. He even tried to kiss Misha back!
Though Misha played hard to get at first:
But then gave up and went in for another kiss:
Of course, Jensen has gotten his lips on Misha before:
So it’s nothing new. ;-)
Anyway, thank you for asking this question.
It gave me a wonderful excuse to think back on Misha/Jensen’s kissing history, which, the fact that they even have a kissing history is awesome. Haha.
