Actor Dwayne "The Rock" Johnson has poked fun at actor-singer Zac Efron.
Efron posted a photograph on his Instagram page to promote his soon-to-be-released movie "Dirty Grandpa".
The image showed Efron flaunting his ripped body in the outfit while having a chat with co-actor Robert De Niro who wore a brown beach shirt and a beach hat.
Johnson cheekily commented on the photograph: "Nice t**s brother. See you soon!"
The "San Andreas" actor seemingly made the comment because the words on Efron's orange top read, "Stop Staring at My T**s."
