The premiere comes after quite the surprise over the weekend, as Depp, Fisher and Breslin were in the middle of a press conference when Justin Bieber made an unplanned appearance.
Walking in just after Johnny answered a question as to whether or not he was a "Belieber," the "Pirates of the Caribbean" actor exclaimed, "Hey, pal! We just established that I'm a Belieber."
To this, Justin replied, "I'm a big fan of you, so I had to come support you. I just wanted to say 'hi.' I heard you were in the building."
Of the Bieber pop-in, Depp later said, "My daughter was most definitely jealous. Justin, bless him, he's a very sweet guy. He had a pair of his purple glasses in his pocket [and] he said, 'Oh yeah, give these to Lily-Rose.' She was very chuffed [British slang for being really pleased] about that. She was very touched."
