FOR SALE Britney Spears’ 5 BR, 5 BTH spread

There’s gold records in them thar hills! Just as Christina Aguilera purchased a beautiful new pad in the Hollywood Hills, rival popster Spears put her hillside abode (above) up for sale. But it’s not because the town ain’t big enough for the both of ’em; Spears is looking for another home in the nabe. Built in 1997, Britney’s gated 8,000-square-footer features a guest house, a pool, and a spa, while Christina’s new digs include a 50-foot cowhide wall and a 30-seat theater. Too bad the two pop tarts didn’t time their house hunting better — they could’ve collaborated on a real estate duet.
