Guac is no longer extra thanks to a charitable food donation from "The Rock."

Dwayne "The Rock" Johnson is cooking up a genius marketing strategy that’s equal parts tequila and giving back to the struggling restaurant industry in time for Cinco de Mayo and his 49th birthday on May 2.

The 10-time world wrestling champion, actor and businessman’s new campaign, "Guac on The Rock" will give out free guacamole nationwide via his own personal Venmo account. Anyone interested can order any style of guac for up to $10 per person purchased alongside a cocktail made with his brand, Teremana Tequila from May 1 through May 5.

"No better way to celebrate my 397th birthday, than with all of us helping our favorite local restaurants get back on their feet, all while drinking some Teremana and enjoying our favorite guacamole," Johnson said in a statement, adding: "I want to help get people safely back into our restaurants, bars and hotels. This is an industry close to my heart and one who normally gives all of us so much support year-round. These people need our help and support to get back in business."
