Gwen Stefani made her musical comeback in October with the heart-wrenching "Used to Love You," and she's nowhere near slowing down. "I think I have enough for probably two albums," she told Zane Lowe in a half-hour interview on Beats 1 (listen below). "I have to write a few more songs, because I feel like, might as well keep going while it's there."

She went on to explain that she has "like 20 songs" and that she completed an album in eight weeks but is planning to keep writing. Here's where she's at:

"There's this crazy thing where I was given this gift—which I didn't know about until it happened—that I could write these songs. But I was always so not confident about it and worried about it, and like writer's block, and all these things, and I was like that. I was so blocked for so long, and making that last No Doubt record was so hard, like knocking my head against the wall … But now it's happening again, and it's like the most incredible thing ever. It's so incredible to be able to use my gift again."

Stefani's last solo album, The Sweet Escape, came nine years ago, although she fronted the No Doubt reunion album Push and Shove in 2012. She announced her divorce from Bush frontman Gavin Rossdale, her husband of 13 years and the father of her three children, in August. It's hard not to read her new single and video "Used to Love You" as inspired by the situation.
