Justin Bieber couldn't resist showing off his toned frame when he went horseback riding in LA's Griffith Park on Monday. The young crooner was joined by a group of friends and initially set on his ride in a white top, which he removed in the middle of his ride. Justin apparently liked his horseback adventure, posting shots of himself on Instagram [1] and asking, "Is that young Indiana Jones? #skintightpants #igottachill"

One person who was not part of Justin's horseriding pack was his mom, Pattie Mallette. However, Justin did have his mom by his side on Mother's Day [2], when they sat courtside at an LA Clippers game and got cute by snapping selfies and sharing laughs.
