Miz Spears was married to one of her former backup dancers, named Kevin Federline. Miz Spears and her ex-mister sold the nearly 10,000 square foot spread for ten million clams shortly after they were divorced in the summer of 2007.

Newly single Miz Spears moved from her Serra Retreat retreat to a couple of rented residences before she rather rashly snatched up the mansion in The Summit.

From the big house in Calabasas, Miz Spears moved on to an even bigger mansion on 3-plus acres estate in the guard-gated Hidden Hills community. The multi-winged mansion (rear shown above) encompasses nearly 20,000 square feet, includes a massive entertaining pavilion with hotel lobby-sized ballroom, and contains a total of 10 bedrooms and 13 bathrooms. Outside the, expansive, high maintenance and fully-landscaped estate offers a private pond, sunken tennis court, and dark-bottomed lagoon style swimming pool with Playboy Mansion-esque spa grotto.

Miz Spears (and family) currently occupy a rented mansion in an upscale, guard-gated golf community in Thousand Oaks, CA. The house (rear shown above), which all sources say she leased, was last listed for sale with an asking price of $8,900,000, measures 10,567 square feet according to listing information we teased up out of the interweb, and includes 5 bedrooms, 6.5 bathrooms and hilltop views of the manicured greens and fairways of the surrounding Sherwood Country Club.
