I <3 Twitter. I think it's the greatest thing ever! Okay maybe not ever but it's finally getting bigger and more people and celebs are using it. (I've been on since Sept. 07.)
Who knows if it's really her. There's an imposter Brandi page. It would be smart of her if it was her and if she actually uses it.
I love how you can follow people, get their tweets on your phone and keep up with friends without actually talking to each other. As well as see what artists/actors are up to, get the latest news updates, gossip, etc.
