"So I'm in the studio writing a freak nasty song and in pops my mom and two aunts. #uncomfortable," tweeted the "Bust Your Windows" singer. "By the way, I'm working on my new album!"
Last January things didn't appear so optimistic for Sullivan. After earning eight Grammy nominations for her first two albums, Fearless and Love Me Back, she decided to step away from music to do a little soul searching.
"I'm trying to figure out who I am without a mike, paper or pen," she tweeted. "I promised myself when it wasn't fun anymore I wouldn't do it and here I am."
Sullivan's third album will undoubtedly send fans into a tizzy.
