The tweet links to this post about Misha owing Kim a kiss.
From dinner, talking about the Justin Bieber T-shirt items-
Me: Oh yeah, you owe Kim (Rhodes) a kiss.
Me: /explains Kim’s demands for a kiss from Misha for taking all those pictures
Misha: Yeah, sure! ‘Cause she’s really hot.
There may have been swearing in there, but he said yes and included “hot” in his reason. I think I figured out what was missing from the phrasing now.)
