So why does she have the desire to share her emotions with over 70,000 strangers who follow her Twitter updates?
"It's sort of like what I would tell a reporter if I were doing an interview," Bynes says. "You kind of have to let people know a little bit about you. And once you've been in the business for a long time, people kind of know stuff about your life."
"I don't tell anybody anything too

things to herself.
"I don't like talking about [dating]," she says. "But when I'm getting married, I'll be open about that."
A Twitter topic she would
