The former Beverly Hills, 90210 star was competing in the Toyota Celebrity/Pro Race, and he saw off competition from Keanu Reeves, Christian Slater and Adrien Brody to take the title.
Singer/songwriter Jesse McCartney and skateboarding star Tony Hawk finished the race early after they were involved in minor crashes on the track, but both emerged unscathed from the accidents.
Green’s on/off girlfriend Megan Fox watched the action from the crowd, and was seen cheering on her man and embracing him after he crossed the finish line.
And after the race, Green was full of praise for his supportive partner, telling E! Online, “Megan is here, I love you. It’s awesome.”
He adds, “I gotta say, I got to give it up to Adrien Brody, we’ve been battling it out the past few days, and he is really a hell of a driver.”
