Justin Bieber was detained at the Los Angeles International Airport yesterday after arriving back in the states from his visit to Tokyo. Although he was held at the airport for four hours, the “Boyfriend” crooner didn’t let it affect him. Upon being released, the Biebs took to Twitter to share the photo above with the caption “All Smiles” as well as some words of positivity. A source confirmed to Us Weekly, that Bieber was detained as a “routine secondary set of questioning that Justin has to go through now every time he comes back in the country because he’s a foreign national.”
