Here's what gets Fast & Furious star Paul Walker running hot - a round of disc golf with his mates.
The star of the hit car chase film franchise stripped off his white T-shirt on Saturday in the sweltering heat on the course in upscale Montecito, California to reveal his chiselled six-pack abs.
After earlier asking on Twitter what everyone's plans were for the Labor Day weekend, the 39-year-old action hero tweeted: 'It feels like a disc golf kind of day,' and then swiftly rounded up four buddies to join him.
