Hayley Williams has been singing in Paramore since their formation in 2004.

In the 15 years that Paramore have been together, Williams has only released one solo single - 2009's "Teenagers" featured on the Jennifer's Body soundtrack.

On Saturday (28 December), Williams shared a statement on Twitter thanking everyone for her 30th birthday wishes, and announcing her solo music plans. She wrote, "I'm putting out some music next year. With the help of some of my closest friends, I made something I'm going to call my own. It's a really special project and you'll get a taste of it in January."

Williams has also featured on a number of other tracks over the years, including songs by B.o.B, Chvrches, Weezer, Tegan and Sara, American Football, and more.

Paramore released their last album After Laughter in 2017.

Hayley Williams is due to release new music in January 2020.
