It's been a tough week for Justin Bieber.
But the troubled teenager seemed happy enough on Friday night as he was pictured grinning when he left a rented Miami mansion.
The self-styled King of Pop was in good spirits, signing autographs for fans while surrounded by bodyguards.
Also with him was his 38-year-old father Jeremy, amid fears that the star's life may be spiraling out of control, and who some have accused of being a bad influence on Justin.
Bieber has apparently refused attempts by his management to check into rehab.
