Raz B announced that he's dropping out of the very successful B2K Millennium reunion tour, just five days in.

B2K is currently on a world tour, along with Mario, Pretty Ricky, Bobby V, Chingy and The Ying Yang Twins - and so far the tour is selling out everywhere.

But Raz B announced last night hat he's dropping out.

"Actually, let me correct myself," he says in a video clip. "Raz B is officially off the tour. I don't feel safe because I feel like Chris Stokes is around. So guess what? I'm off the tour. Good luck to everybody. No disrespect to [Omarion] because he's my brother. [Omarion] if you want to come talk to me and you want me to do the tour, I'll do the tour, but I'm officially off the tour." Raz then goes on to say, "Oh, guess what? I guess we're about to shoot the new 'Surviving Chris Stokes' movie, right? So call Lifetime 'cause I'm ready to talk."

Here's video:

A few years ago, Raz B accused Chris Stokes of sexually molesting him as a child. Raz B subsequently retracted the allegations, and claims that he was suffering from mental health issues at the time.

It's not clear why he doesn't "feel safe" around Chris now . . .

But, according to HotNewHipHop, here's more tea:

For over a decade, Raz has accused former B2K manager Chris Stokes of molesting him, saying that the alleged abuse began when he was around 11 or 12-years-old. "It all started with Chris Stokes," Raz said in a video back in 2007. "It started one day when Chris was like — 'Let me touch you'...I can't speak for everybody, but if you want my personal opinion, I think he did (touch all the other group members)." 

Raz's brother, Ricardo Thornton, also claims that Stokes sexually abused him. "Chris [Stokes] made me take showers with the other boys...All that little sh** that my brother was introduced to, that sh** was brought to me first, and I blocked that sh**. I wasn't with it, I backed off...I kinda knew what was going on over there, and yet I took my brother over to Chris. I didn't protect him like I should have. [Stokes] molested my brother and he molested me."
