The WWE superstar is boasting on social media about the financial success of his latest film, Fast and Furious spinoff Hobbs & Shaw - days after Gibson mocked its box office results.
"The best way to shut the mouth of a clown is to flex with success and a smile," Johnson tweeted.
"Thank you everyone for making this an exciting first week of box office for our little spinoff Hobbs & Shaw - number one movie and US$333 million worldwide ain't too shabby."
