Okay, so they're not wearing much, which is sort of the point.
The Fast and the Furious star Walker -- they've just started working on the SEVENTH installment of the action hit -- was photographed in a Santa Barbara park playing disc golf with his daughter and some pals.
The Lucky One star Efron is filming a new flick, Neighbors, and the producers were so taken by a shot of their shirtless leading man during an outdoor barbecue scene, they released a pic even though the comedy isn't hitting theaters until next May!
Who do you think looks better with his shirt off - Walker or Efron? Tell us in comments.
