Justin Bieber is on his workout game and his focus on fitness could be seen when he stepped out on Wednesday (January 3) in West Hollywood, California after a private pilates session with Selena Gomez.

With a smoothie in hand, the Biebster showed off his toned physique in an all-white outfit as he made his way through the parking lot. See more shots of the star below. Bieber and Gomez's workout outing comes after rumors that the reunited couple spent New Year's Eve together in Cabos San Lucas, Mexico. According to reports, the occasion was a "low-key" one, with the pair ringing in 2018 on the beach.

"Justin flew in to Cabo on a private jet from Cancun where he spent a few days with his family," a source told E! News. "He arrived on Saturday evening and checked into an oceanfront villa 10 minutes away from Selena‘s villa where she was staying. He and Selena spent time together again. They were very low-key and dressed casually. They rang in the New Year together and enjoyed watching fireworks over the ocean."
