judging from the pic on max's blog site, the first pic should be max... in mika's blog the first sentence was "この週末、三人で旅行をしました。" It seems like it's about three people traveled together.. so probly TH is right... that semi-naked guy in mika's blog should be max..
Edit: the sentence after "three people traveled blah blah blah" is
ウソです。当然他にもスタッフがぞろぞろ... it's funny
PS: I always thought Max's an old guy (like mid 50s or 60s).. never expect he's that... "young".. @@
