Justin Bieber must’ve started a trend or something, because discussions of male celebrity posteriors seems to be at an all-time high.First of all, there’s apparentlyan annual award in the U.K. celebrating the best in British butts that’s been going on for nearly 40 years.

None other than “Harry Potter” star Daniel Radcliffe, who’s no stranger to baring his derriere on stage and in film since graduating from the kid-friendly wizarding franchise. “I’ve been campaigning for years,” Radcliffe admitted to E!

He also was kind enough to offera bit of an acceptance speech, promising to “get it out a lot more in the future.” Cheers, lad!
