Justin Bieber tips his hat while riding horseback shirtless with friends on Monday afternoon (May 12) in the Hollywood Hills, Calif.
Earlier in the day, the 20-year-old entertainer threw up a peace sign while leaving his hotel in Beverly Hills.
Justin Bieber is definitely proud of those abs of his and wasting no chances to show off his washboard stomach once again, the Baby superstar whipped off his top to enjoy a shirtless horse riding session in the Hollywood Hills yesterday.
Justin may have been one of a group of people that was snapped on horseback this week, but he seemed to be the only one that went topless, with him also failing to wear a helmet for the outing.
