In Buzzed, we take a look at three things that trended over the weekend while you were away from your keyboard getting buzzed.

On Twitter

Is Britain's prime minister, David Cameron, the newest member of One Direction? No, that would be completely implausible and stupid, but according to a tweet sent by him, he's cameoing in a upcoming 1D music video for charity. Aren't you glad you know that?

On Vimeo

So, apparently there's some beef between rapper Azealia Banks and "Harlem Shake" producer Baauer. Banks posted a remix of the song on Soundcloud, which annoyed Baauer, who then got the song pulled, reports Stereogum. Determined to let the masses enjoy her version, Banks posted a video of the remix on Vimeo on Sunday. Baauer hasn't yet responded.

On Tumblr

In a blink-and-miss-it moment, Vampire Weekend lead singer Ezra Koenig briefly appeared on this weekend's episode of Girls. A fan blog posted the clip on its Tumblr and we have to laud him for nailing the role of a guy who just stands there.
