I don't think this will work out.
Despite the taunt of Justin Beiber and even Connor Mcgregor, I don't think Tom Cruise would even fight JB in an octagon, it will just be a Tom Cruise vs. Sandbag-who-can-sing bout. I do like to watch JB being punched and dragged all over the octagon, I think every guy get that idea, I don't know, I am not a hater of Justin but I do like that to happen.
SO yeah, JB just backed out saying excuses as he'll be having his ass kicked by TC.
There's nothing serious about this, though the message was been read by millions who's following both this stars, but for TC's part is nothing but a
open publicity for JB and he's not gonna buy this, he have his entire clean career so there's no need to interact to something that won't help him out,
it will just be forgotten and be gone with the wind.
