Justin Bieber Warns Fans to Stay Away from His Hotels

Pop superstar Justin Bieber has warned his fans to stop trying to gain access to his hotel room, after footage of young girls storming a building emerged online.

The Baby hitmaker is currently touring South America and is staying in Argentina ahead of his show at the River Plate Stadium in Buenos Aires on Thursday.

Hundreds of young devotees discovered where Bieber was and flocked to the hotel - and scenes of chaos were screened on local TV news stations as fans tried to gain access to the building.

The teen superstar saw the footage, and took to his Twitter.com page to write, "My Fans go Hard!! ha. Epicfans !!! wait... but dont break into my room. that aint cool. this is still epic."

Selena Gomez (Getty) Selena Gomez got to join her beau Justin Bieber in Brazil for the last week or so, but now the two are again continents apart. Gomez had to head back to the US a few days ago in order to get ready for the Canadian leg of her tour, while the Bieb still has plenty of tour dates in South America.

Last night, one of their first apart, Gomez rocked sparkly shorts and a flowing chiffon top for the premiere of The Thing in LA, while her man was back in Brazil performing for a packed stadium. Bieber sang for fans in Porto Alegre last night, after singing in Rio a few days ago. He'll head to Argentina next.

We bet it's hard for these two to be apart, but they're also very used to it. And enjoy the time they do get together -- especially since it usually includes helicopter rides and more fun stuff. Gomez tweeted after heading back to the States: "Brazil, I love you all. You have all been amazing to me while I have been here and I will be back soon. :)"
