Justin Bieber Goes Hiking With Sexy Model Jayde Pierce

Justin Bieber cozied up with model and make-up artist Jayde Pierce while they went hiking in Runyon Canyon, Los Angeles on Sunday, May 17. The 19-year-old model posted on Instagram a photo of her and the "Baby" hitmaker.

In a Snapchat video shared by Jayde, Justin went shirtless while walking backward. Jayde could be heard laughing in the video. In another video, the shirtless "Boyfriend" singer gave the sexy model a piggyback. "Yay we made it to the top!" Jayde said in the video, "He carried me halfway through but that's fine."

A fan who later spotted Justin outside a restaurant asked for a picture but the singer declined because he said he had to take Jayde "safely" into waiting car.
