Hmmm, I'm not sure it is. It seems fake because there's a tweet about getting the account verified soon and then on Adam Senn's and Eva Herzigova's supposed twitter...it says almost the exact same thing. If you look closely...it looks to me like all of those accounts are the same person posing as them. Also, the way the posts are written seem pretty immature to be honest. There's more that I can say that lead me to believe it's fake, but I'll just leave it at that...I'm getting off topic.
Thanks for posting the pics above, though! He's gorgeous as usual!
