Paul Heyman has been tweeting during UFC 181 tonight but only re-tweeted other comments from fans about CM Punk signing with UFC. Here's one of the tweets Heyman re-tweeted:
It looks like Rey Mysterio is the only WWE Superstar to comment on Punk's signing so far. He congratulated Punk and wrote the following on Instagram:
"Awesome to see my homie Punk at UFC 181 announcing his new career as a UFC fighter! Congrats & wish him the best... Kick some ASS homie! #ItWasAPleasureBeingInTheRingWithU#LifeChanger#CantWaite2SeeUKickAss"
