When Justin Timberlake broke into a prison

Justin Timberlake once "accidentally broke into" Alcatraz prison. The 39-year-old singer has revealed that in 2000, he was filming a music video with boy band NSYNC near Alcatraz Island when he and his bandmate, Joey Fatone, snuck into a guided tour of the maximum security prison, which closed as a jail in 1963 and once housed infamous crime boss Al Capone.

Explaining the story during an appearance on 'The Ellen Degeneres Show', Justin said: "I accidentally broke into Alcatraz one time. I was in a group called NSYNC ... We were shooting a video in the redwoods outside of San Francisco, and we ended up shooting this one scene on this pier directly opposite Alcatraz.

"And at the time I was watching 'The Untouchables' over and over again, and I was obsessed with the fact that Al Capone, you know, they put him in Alcatraz.

"And I said: 'Who wants to go see Alcatraz with me?' and Joey - who's usually game for anything - he was, like,: 'I'll go with you!' but we only had, basically, an hour in between where they were setting up a different shot.

"So the fire department was waiting around and they came up and said: 'Hey! Could we take some pictures with you guys?' and Joey and I were, like : 'Sure ... would you take us to Alcatraz?'

"They were, like: 'Yeah, sure!' So they take us over - we felt so cool - on like a coast guard, fire department boat."

Justin and Joey were then taken to the island, not realising that those who visit the island via tourist ferry have their tickets checked when they arrive on the island.

And without tickets, they decided to sneak into the prison instead of joining the tour.
