Dwayne Johnson Flexes After Hernia Surgery [PICTURE]

Dwayne Johnson underwent emergency hernia surgery, but even that couldn’t keep "The Rock" from flexing his muscles.

“Surgery a success!” Johnson tweeted Tuesday while showing off his comic book character-frame in a Superman t-shirt. “Dr repaired 3 hernial tears (fun pain). Superman is on the mend.. #WeFallWeRise.”

Unfortunately, Johnson's surgery caused him to miss the Los Angeles premiere of his new movie, Pain & Gain, which also stars Mark Wahlberg and Anthony Mackie and hits theaters this Friday. The movie’s director, Michael Bay, made the best of the situation by taking a jab at the wrestling star.

“He was pushing it too hard,” Bay told E! News. “[He] needs to grow up and stop wrestling 300-pound men.”

“Funny sh*t!” Johnson tweeted upon hearing the news. “Michael Bay joked I should stop wrestling 300lb men. I agree – I'll switch to women. #ALLPainNOGain”

It’s been a hectic year for Johnson, 40, who has already starred in two movies in 2013: Snitch and G.I. Joe: Retaliation. In May, Johnson teams up with Paul Walker and Vin Diesel in Fast & Furious 6, and later this year he'll star alongside Liam Hemsworth in Empire State.
