Rihanna Lived in This $52 Million London Penthouse

It's easy to see why this $52 million London penthouse—the largest on the market in the city's Knightsbridge district—has been an A-lister favorite. Once home to both Rihanna and Tom Cruise (though not at the same time), the 10,000-square-foot residence occupies the top floor of a historic 19th-century building, formerly the Second Duke of Wellington’s Riding School and is the largest penthouse on the market in the city’s Knightsbridge district. Within the 10,000-square-foot interiors, which occupy an entire floor, there are mirror-lined ceilings and black parquet floors. Highlights include a music room with a Swarovski crystal–lined bar, a study, a double-height formal dining room, and an expansive living room, which opens onto a terrace. There’s also a large kitchen with onyx walls and African black marble counters, a media room, a gym, a spa with treatment rooms, and a Juliet balcony. The master suite, one of six bedrooms, showcases views of Hyde Park. The sprawling terrace spans the length of the rooftop. Listed for approximately $52 million, this 10,000-square-foot home has 6 bedrooms and 6 baths. Contact: Wetherell, +44-20-7493-6935.
