The Week In Celebrity Tweets

The wonderful world of Twitter welcomed its newest famous member this week: Bill Clinton.

On Wednesday, the 42nd President of the United States officially took over the account started by Stephen Colbert and changed the handle from @prezbilljeff to @billclinton (though some would argue the former was a better name).

Meanwhile, Amanda Bynes’ latest Twitter photo and announcement concerned her hair. Channeling singer Cassie, Bynes’ half-shaven head is the “new” her, and she loves it, no matter what her critics think.

In the music world, Rihanna and Katy Perry had an interesting online exchange, resulting in RiRi promising “spanking” rights to her BFF. Mariah Carey’s daughter raided her closet, Harry Styles shared his favorite Grease scene and Justin Bieber told his fans he’s focusing on music instead of all those rumors.
