AP: When you sang "At Last" for the Obamas at the inauguration ball, Etta James said some pretty harsh things about you but later said she was joking. Did you know she was joking?
Beyonce: I played Etta James (in last year's "Cadillac Records"), so I did my research, I read her book. I was not at all surprised. That's Etta. She's hilarious (laughs).
AP: Your sister Solange twitters all the time. Do you do it?
Beyonce: My sister is the Twitter queen. She told me about the twittering, but I don't get it, I feel like I'm getting really old. I'm like, what? I don't understand. Just call me.
