Where celebrities live is very important to them. Their multi-million dollar real estate investments need to produce only the most lavish amenities that their money can buy; whether their needs include room for their growing families, private terraces, nanny quarters, or sweeping city views. Tom Brady and Gisele Bundchen have started construction on the $20 million mansion in Brentwood, California (seen above) according to Curbed.com, while still trying to sell their pricey Boston condo. Taylor Swift bought a $2.5 million Greek Revival mansion in Nashville, Tennessee and Alec Baldwin moved into a Greenwich Village penthouse for $11.7 million. Their addresses might change often, but their desire to spend big bucks on the perfect home sweet home will continue on.
