Justin Bieber Again Smokes Weed At Amesterdam Coffee Shop.

On Monday Justin Bieber made a pit stop in Amsterdam during his world tour, and a source claims he was spotted smoking marijuana at a coffee shop.

First he visited club De Melkweg where he tried to reserve a table, but he was turned away because the venue was too crowded. He later went to a coffee shop called Easy Time, and a source told PerezHilton.com he smoked a joint and ate a pot-laced treat known as "space cake."

The singer also went to a gift shop and purchased some gifts for himself, friends, and family, including a joint holder.

It isn't the first time Bieber has been caught up in a marijuana scandal. In January, a photo leaked showing him smoking pot at a party inside a Newport Beach hotel in California.
