Actor & Actress friendship

I want to know who're your fav friendship of actor-actress

My fav :

Toda Erika - Matsuda Shota ( i heard they're being BFF since Liar Game)

Nikaido Fumi - Suda Masaki (eccentric BFF)

So who's yours?

@blueribbon: I've read somewhere, sometime, that Toda and Matsuda didn't get along, reason why she wasn't on the last Liar Game movie/SP and reason why Tabe Mikako replaced her. I've read that it was because Matsuda was too cocky? something like that.
