The Game is stepping up to get in a boxing ring with George Zimmerman -- and this is no joke to the rapper ... who, by the way, has a tattoo of Trayvon Martin. Game joins us to prove how serious he is. 

Plus, a new Justin Bieber investigation -- but this time it's a Miami Beach police officer who might have screwed up!

And, "Ghost Adventures" host Zac Bagans joins us to explain why he bought house that's supposedly a portal to hell.
