You may have seen the #BottleCapChallenge taking over the internet. Justin Bieber is one of the latest to do it and he used this to get a dig in at Tom Cruise. If you recall, Justin publicly challenged Tom to a fight.
The other major celeb to give the challenge a go is Mariah Carey! And fans are saying she won the entire thing so everyone else can just give up LOL! What do you think?
