Not long before Canadian pop-rocker Avril Lavigne and also Canadian Nickelback frontman Chad Kroeger announced the end of their two-year marriage in the fall of 2015, via Instagram, they shelled out $5.4 million for a decidedly traditional chateau-inspired mansion in a beautifully leafy, upscale neighborhood of Sherman Oaks, Calif., that’s now back on the market at $7.999 million. Partly obscured by mature trees and secured behind high, vine-encrusted walls and imposing wrought iron gates, the late 1980s faux-chateau measures in at about 10,200-square-feet over three floors with six bedrooms and 7.5 bathrooms.
