Justin Bieber is on daddy duty. On Monday, Aug. 18, the singer, 31, shared an Instagram carousel featuring new photos of himself and his 11-month-old son Jack Blues, whom he shares with his wife Hailey Bieber. In the pictures, Jack, who turns 1 on Aug. 22, sat back on a large cushion as his legs dangled on his father's shoulders.

When Justin Bieber appeared onstage at a Las Vegas nightclub last week for a surprise performance alongside a popular DJ, the crowd — and the DJ — went wild.
