Steven Tyler, Paula Abdul, Lena Dunham + More in Celebrity Tweets of the Day

Today (May 23) celebrities lost instruments, worried about porn, studied toilets, spit platitudes and pigged out.

First up, you don't have have to learn about toilets. Bill Gates is doing it for you!

Paula Abdul either inspired or confounded, depending on who you ask.

Meanwhile, LeAnn Rimes was enjoying some fried foods.

And have you seen Steven Tyler's Texas harmonica? Let him know. He's very worried.

And, finally, there's a 'Girls' porn parody coming out. How does Lena Dunham feel about that? Not great.
