Big Show has been training for their big showdown at WrestleMania 33 in April -- after months of smack talk.
Now, Big Show is showing off his progress with a gym pic and a message mocking Shaq who's been spotted at an Oreo cookie event recently and lip-synching on Instagram.
"@Shaq! Karaoke? Doughnuts? You better get serious. All roads lead to @WrestleMania. The only giant!"
You know what this means? SHAQ'S GOTTA SELFIE BACK!
