The 'What You Waiting For' hitmaker has gushed about her new relationship with the 39-year-old singer, admitting it has inspired her songwriting.

When asked if she is in love now, she shared: "Yeah, for sure. I don't really want to go into that relationship, and God knows what's going to happen.

"But I feel like I'm in an amazing songwriting place; instead of being closed off, I'm thinking about positivity and how I can do something creative. I'm just doing what I want to do. It's so incredible to be in that zone. I'm always looking for the next song, and now I don't have to be insecure or write about heartache."

The 46-year-old singer also admits she struggled to get back in the studio following her split from Gavin Rossdale.

She added to Vanity Fair magazine: "I was so scared and insecure and thought it was over for me. I think the hardest thing I did was to get out of bed and go to the studio.

"I went through a real period of anger, but I felt like this song ['Used To Love You'] was almost like a forgiveness song. It's admitting, I used to love you and now I don't. I opened this channel to writing again - it was me being honest, being real."
