Charli XCX performs during the 2013 Bonnaroo Music & Arts Festival on June 14, 2013 in Manchester, Tennessee.

Charli XCX's debut album, "True Romance," was just released in April on IAMSOUND Records, but the U.K. pop singer-songwriter is already prepping new material for her sophomore LP.

"I am starting to write the second album," the 20-year-old artist told Billboard following her performance at the 2013 Bonnaroo festival last Friday (June 19). "Two months ago, I wanted to go to India and record it, and now I want to record it in France. So I feel like nothing is definite -- like, I feel very all-over-the-place at the moment. But at the moment, my heart's set on going to France and recording it, but that was different two months ago, so who knows what's going to happen?"

The singer has received critical acclaim for "True Romance" -- which includes breakout singles "You're The One," "Nuclear Seasons" and "You (Ha Ha Ha)" -- and recently wrapped a tour showcasing the album in support of Marina & The Diamonds. On Tuesday, Charli XCX announced an expansive headlining trek that will run throughout North America in the late summer and early fall.

"This is gonna be a proper headline tour throughout the States, and I'm really excited about it," says the singer. "I feel like it's gonna be the first time where I really stepped up production, really thought about the 'show' aspect of my live performance, which is really important to me."
