With a $22 million price tag, The House of Rock mansion is worth every penny: six bedrooms, eight bathrooms and a state-of-the-art recording studio all on the 11,000-square-foot property!

As The Agency's Celebrity Real Estate Agent, Mauricio took our camera crew through the halls of the opulent pad, which were once frequented by the likes of Judy Garland, Frank Sinatra and Howard Hughes. Nowadays a new crop of stars -- Babyface, John Legend and Christina Aguilera -- have kept up the tradition, according to The House of Rock co-founder Jennifer Vernon.

While the house has been around since the good ol' days of Hollywood's golden era, it has kept up with the times through a makeover by owner and designer Elaine Culotti. Mauricio found one current feature particularly intriguing -- a TV built into a bathroom mirror.
