Kyrie Irving may have occasional beef with his Boston Celtics teammates, but he's sworn it out of his diet.

The Boston Celtics guard is starring in a new ad campaign for Beyond Meat, a health food company that produces plant-based meat substitutes. The company's investors include several notable current and former athletes, including Shaquille O'Neal, Chris Paul, DeAndre Hopkins, Victor Oladipo, Lindsey Vonn, DeAndre Jordan and Harrison Barnes.

But Irving is the face of the company's digital campaign, starring in a one-minute ad for Beyond Meat that launched Wednesday.

All-Star point guard @KyrieIrving is kicking off our new #GoBeyond campaign which spotlights the spirit & drive needed to reach the unattainable, the same spirit that propels our mission to perfectly build meat directly from plants.

Irving admitted at the beginning of the 2017-18 season he had switched to a vegan diet that made his body feel "amazing." In a recent interview with The Los Angeles Times' LZ Granderson, Irving said Beyond Meats started sending him samples after he went public with his diet switch.

"I was noticing that I wasn’t able to recover as fast after games and workouts,” Irving told Granderson. “I did a lot of research and learned that my diet could be a factor.

"It was good timing as I was struggling to find quality plant-based foods that still had a lot of flavor."

The 26-year-old apparently was sold on the product and is now spreading the gospel: He often rocks a hat featuring Beyond Meat's caped steer logo during pre- and postgame interviews.

Now, Irving is the centerpiece of Beyond Meat's "Go Beyond" campaign, the company's first substantial ad campaign since it launched in 2009, per AdAge.

Celtics fans may prefer Irving talks in commercials instead of on ESPN; the All-Star guard gave a candid assessment of the Celtics' chemistry issues in an interview with Rachel Nichols that ran Wednesday.
