Justin Bieber is the first artist EVER to reach a whopping 50 MILLION subscribers on his YouTube channel following the release of the first track "Yummy" off his new album Changes. Listen as our pap congratulates our favorite pop star as he leaves the Voda Spa in West Hollywood yesterday morning.

Later in the day, Justin was decked out in green as he and wife Hailey Baldwin boarded a private jet in Van Nuys, CA. In additional to prepping for his upcoming tour, the 25-year-old superstar will be making a very special appearance on Saturday Night Live this weekend. We can't wait!
