Charles Spencer lives in a grand home in Northamptonshire known as Althorp House, and he left fans stunned after sharing a new look inside. SEE: Princess Diana's childhood home Althorp House ...

The Irving Spencer House, the oldest surviving residence ... To the left is the music room, now used as a dining room, that also has oak parquet floors as well as eight-foot-wide pocket doors.

Earl and Countess Spencer transformed the State Dining Room at Althorp House into a magical candlelit scene to mark what would have been the late Princess Diana's 62nd birthday on Saturday.

Countess Spencer retreated to the Mayfair townhouse, a stucco-fronted five-bedroom Georgian house. She had painted the dining room the same bright red colour as the dining room in Althorp.
