(CNN) -- Hilary Duff says her new album is "very positive" but admits that it started out "a lot heavier and a lot darker" because of the separation from her husband, Mike Comrie.

"I'm separated from my husband right now, which has been a very difficult thing to go through," she told Billboard's "Pop Shop" podcast. "In the beginning, the album was a lot heavier and a lot darker, because I had to get that out. Once I did get that out, a lot of fun came."

Duff married Comrie, a former pro hockey player, in 2010 after dating for three years. Their son, Luca, was born in 2012. Duff and Comrie announced their separation in January.

Duff, 26, admits that she's "nervous" after being away from music for seven years. Her just-released single, "Chasing the Sun," is from her still-untitled album, which will be her first studio release since 2007's "Dignity."

She says she first started thinking of new material when she was pregnant with her son. After having the child and taking another year, she was even more anxious.

"I felt like I was missing a big part of myself," she said.

Duff established a successful singing career on the heels of her popular Disney show, "Lizzie McGuire," which aired from 2001 to 2004. She spent most of her teenage years touring and says that turning 20 was a big factor in leaving the road.

"It was time for me to be a person, and the break just ended up being a long time," she said. What are the answers to this following set of questions: 1. Is Hilary's newest album negative?

Guardian Centers may be a place to practice how to respond to a disaster, but that doesn't mean real danger is nonexistent.

When we headed over to see its mock subway station, complete with eight cars donated from Washington's Metro system, we were told we had a limited window to view it. The reason -- they were going to be pumping actual toxic gas into the building to simulate a chemical attack.

As smoke rose from chunks of concrete representing an obliterated building, Chris Schaff put it this way: "As soon as you come in here, the pretend goes away."

He's a fire and rescue battalion chief with Fairfax County, Virginia, and his words carry a lot of weight. His elite team of urban search and rescue operatives has been deployed to numerous disasters, including Hurricane Sandy, the 2011 Japanese earthquake and tsunami, and the 2010 Haiti quake.

Luis Fernandez, a two-decades-plus veteran of disaster response, agreed the Perry, Georgia, facility passes muster.

"The temperature extremes, the building extremes, the noises, the environment, are incredibly lifelike," said Fernandez, Miami-Dade Fire Rescue chief of staff and.a spokesman for the Federal Emergency Management Agency.

The brotherhood of Disaster City

From the aforementioned subway station, to a mock bridge with crushed cars, to a devastated structure made to look like the aftermath of the Oklahoma City bombing, Guardian Centers' 830-acre site is designed to allow a variety of responders to do a variety of drills in one location.

This kind of "doomsday Disneyland" owes its vision to Geoff Burkart, a telecommunications executive who was in Louisiana in the aftermath of Hurricane Katrina. During Katrina, he saw "what was being done there, and what was not being done." What are the answers to this following set of questions: 1. Who is a 20 year veteran?
2. veteran of what?
3. where is the center?
4. wher edoes he normally work?

Although she's quite young, Drew Barrymore can be a Hollywood legend . She was born on February 22, 1975, in California. Being from a family that produced great actors, she quickly found her way into the spotlight . When she was 11 months old, she made her first advertisement on TV.
