Perhaps nobody had a bigger holiday weekend than Justin Bieber, who made his triumphant return to the new release rack on Friday (November 26) with My Worlds Acoustic, a collection of stripped-down versions of songs from Bieber's first two releases (as well as the new single "Pray"). Bieber was everywhere, chatting on "Today," premiering his new video, unveiling a new trailer for his upcoming film "Never Say Never," signing copies of his album and combing his hair in a different fashion that suggested that he might have gotten a haircut (which caused quite a stir on Twitter). When his cruise through New York was finished, he headed for the U.K. for a promotional tour through Europe, but on Sunday (November 28), he managed to show up in an unusual place: In the mansion of a Brazilian drug lord. 

Of course, he wasn't actually there in the house — rather, he appeared in a giant wall mural inside the enclave of Pezao, one of Rio de Janeiro's biggest traffickers. According to The Guardian, more than 2,600 heavily-armed police officers raided Complexo do Alemao, a huge network of slums that also houses some of the city's biggest drug villains. The violent exercise left 50 people dead, but the Rio police have declared the project a victory.

In addition to finding 10 tons of marijuana and a small arsenal of weapons (which included one missile), there was also a crude homemade mural of Bieber that read "One Time" below it. It's probably the strangest place Bieber has shown up, but it's proof positive that the 16-year-old Canadian singer is indeed a worldwide phenomenon.
