It appears that famously bratty pop-punk princess Avril Lavigne, now 30 years old, may have ended her self-imposed Parisian exile. According to both real estate yenta Yolanda Yakketyyak and veteran celebrity property snitch Lucy Spillerguts, it was Lavigne and her second husband, Chad Kroeger — goateed frontman for the incessantly scorned yet spectacularly successful Canadian rock band Nickelback — who, via an inscrutably named Vancouver, Canada-based corporate concern, shelled out $5.4 million for a rather matronly, family-sized faux-chateau in a leafy estate section of the L.A.’s increasingly affluent, proto-suburban community of Sherman Oaks.

BUYERS: Avril Lavigne and Chad Kroeger

LOCATION: Sherman Oaks, Calif.

PRICE: $5.4 million

SIZE: 7,888 square feet, 6 bedrooms, 7.5 bathrooms

The faux-quoined pile, certainly ample but hardly humongous at 7,888 square feet per listing details, was originally built in the late 1980s on a 0.62-acre lot and has a multi-camera security system and a double-gated circular drive plus a separate, gated motor court that wraps around two sides of a semi-detached three-car garage. A circular drive curves tightly by a double-stacked colonnade that defines the front façade and grandly marks the main entrance to the recently refreshed residence. Medium-brown wood floors in the double-height foyer, complete with wrought-ironed railed double staircase — a suburban macmansion architectural cliché if there ever was one — extend into an also double-height formal living room with carved stone fireplace and overmantel and multiple French doors set into a double-stacked wall of windows. There’s a second carved stone fireplace in the banquet hall length formal dining room that adjoins — booze lovers will appreciate — a walk-in wet bar with dishwasher and ice maker. The comfortably commodious combination eat-in kitchen/family room has a painted coffer ceiling, antiqued raised panel cabinetry, speckled taupe granite countertops and white subway tile back splashes, a walk-in pantry, and a boxcar-sized center island with prep sink and four-stool snack bar. The extensive collection of high-grade appliances include a built-in coffee/espresso machine, three dishwashers and two refrigerators plus a couple of refrigerated drawers, while the family room area has a built-in entertainment unit with large, flatscreen TV and a bank of French doors with direct access to the backyard.

The mini-mansion’s half of a dozen, all en suite bedrooms and total of 7.5 bathrooms include a main floor guest/staff bedroom and a spacious upper-level master suite with fireplace and at least four Juliet balconies accessed through ceiling-height French doors. There’s also a walk-in closet — would anyone be surprised if Missus Kroeger busted through to one of the adjacent bedrooms and converted it to a glammy boudoir/dressing room? — as well as a bathroom sheathed in buttery beige tiles and outfitted with a double-sink vanity, soaking tub and a separate, glass-enclosed shower. Other amenities and luxuries include an upper-level office with built-in cabinetry and Juliet balcony, a main floor fitness room with at least one fully mirrored wall and, perched atop the garage in a space with high, steeply sloped ceilings, a 3-D capable and surround sound enabled screening room and a candy bar with ice maker and two under counter beverage coolers. Given the not-exactly immense lot, the bulk of the residence and the generous amount of space devoted to driveways and parking areas, the pancake flat backyard isn’t especially expansive but does manage to squeeze in a variety of features and functionalities that include a deep flagstone terrace off the kitchen with built-in heaters and a louvered trellis for sunlight modulation. There’s also a gas fireplace and a fire pit, an outdoor kitchen, sports court, a patch of well-watered lawn, and a sunbathing terrace alongside a heated, dark-bottom swimming pool with inset spa.

Mister Kroeger formerly owned an 18-plus acre estate in Abbotsford, just outside of Vancouver, that he sold a few years ago for an unknown sum. The property was featured some years ago on MTV Cribs and, at the time, the 10,000-plus square foot adobe had six bedrooms, five bathrooms, indoor and outdoor swimming pools and — natch — a recording studio. Avid celebrity real estate watchers know this is not the first Los Angeles mansion owned by Miz Lavigne, a multi-tatted eight-time Grammy nominee and three-time American Music Award nominee who, although she’s sold tens of millions of albums and had a string of No. 1 Billboard hit ditties, has been a bridesmaid and never a bride at most of the Big Daddy industry awards ceremonies. Over the summer of 2004, the heady heydays of her early, teenaged fame, the kohl-eyed alterna-rocker who has decidedly traditional or some might say middlebrow real estate tastes, shelled out $4.55 million for a 6,864-square-foot vaguely Italianate villa in the guard-gated and celeb-stocked Mulholland Estates enclave in the mountains between Beverly Hills and Sherman Oaks. In March 2007, almost a year before she sold her Mulholland Estates digs for $5.2 million, she paid Travis Barker and his occasionally volatile former beauty queen ex-wife Shanna Moaker $9.5 million for a 12,184-square-foot mock-Med manse in the guard-gated Bel Air Crest development that she sold in January 2012 — at a million dollar plus loss, not counting upkeep, improvements and real estate fees — to professional basketball player Chris Paul.
