Williams and her band mates have been writing demos for their new album, following the departure of former members Zac and Josh Farro late last year.
And once their new tour wraps up this month, they're heading back in to the studio.
"We are going to go tomorrow to South America to do a tour. And then when we get back, we're hoping to record a batch of songs to release over the summer," Williams told AOL Music.
"All the details aren't worked out yet, but we definitely do want to release [new song 'In the Mourning'] and some other ones before we put out a record."
