Katherine Heigl lists sprawling Utah ranch for $10.6m after ditching Los Angeles 18 years ago

Katherine Heigl is downsizing and listed her custom-built mansion set on 25 sprawling acres for $10.6 million.

The former star, 47, and her husband, Josh Kelley, 46, plan to move into another smaller Victorian home they bought last year and renovated that's not far from their current home, according to The Wall Street Journal.

The home is 8,000 square feet and boasts five bedrooms and seven bathrooms.

Heigl and her husband have lived in the home for 18 years and raised a family, which includes daughters Naleigh, 17, and Adalaide, 14, and son, Joshua, nine.

'It's been very hard to decide to let it go. I'm a real sort-of homebody and creature of habit,' she told the outlet.

But Heigl, who earlier this year, already seeing what the future will be like when the kids move out and that prompted her and the Georgia Clay singer to decide to part ways now rather than later.

'When they're all gone—all slaying their own dragons and living their lives—it's just you and me in this giant house on this giant land,' Heigl surmised.

The animal activist paid $1 million for the land in 2007 before marrying Kelley in December of that year in Park City. They starting building their dream home the following year.
