Hilary Duff is back releasing new music after a seven-year hiatus.

The actress and singer, 26, told Billboard for its Pop Shop Podcast that she was "nervous" to get back into the studio. Her first single "Chasing the Sun" was released earlier this week.

"It's been seven years for me, so I hope -- that what I'm writing and what I'm singing and how I'm singing and my taste and the content -- I hope it's what people that have been my fans or that are my fans are going to respond to ... and I think they will," she told the magazine.

Duff is also a mother to son Luca, 2, and she and her estranged husband Mike Comrie have been dealing with a separation the couple announced in January.

"I'm separated from my husband right now, which has been a very difficult thing to go through, but we have a lot of love for each other and we have this beautiful baby," she said.

Duff and Comrie have still been seen together since the split, and the singer has said they are still trying to figure out their future.

There's a song on the album "about my separation and my love for this person, that maybe we're not meant to be together, maybe we are. It's very, very personal," she added.

Earlier in the year, Duff also addressed the fact that she and her husband were separated but still seen hanging out.

"We are constantly seen together and everyone's like, 'What are they doing? Are they back together, are they not?'" Duff told E! "We are really good friends and we have so much respect for each other, and, obviously, Luca is our No. 1 priority."

She continued, "We love each other so much and we love spending time together. So when you see us out it's not just for Luca, it's because we make plans and we hang out. And we don't know what our future looks like right now, but we're both doing really good and just figuring out what makes us happy."
