Dwayne “The Rock” Johnson puts his huge bicep on display while flexing for a good cause!
The 45-year-old actor was nominated by Jessica Biel to participate in The USO’s Flex 4 Forces movement, to show support for servicemen and women and their families for Independence Day.
“Introducing ‘Jack’ of the ‘Hammer Bros’ to @JessicaBiel & @The_USO. U don’t wanna meet ‘Sledge,’” Dwayne tweeted with the photo.
The Rock nominated Chris Pratt to be the next celeb to participate in the movement and we can’t wait to see his photo!
