Keira Knightley buys USD 5 million marital home?

London: After getting engaged to her rocker boyfriend James Righton, actress Keira Knightley has reportedly splashed out on a USD 5 million marital home.

The 27-year-old`s spokesperson recently confirmed she had accepted the Klaxons rocker`s proposal following a 15-month courtship.

Knightley has apparently bought a USD 5 million townhouse in Spitalfields, East London. The four-story home boasts a cinema, dressing room, library and a music room. It also has a studio house in the garden, reported Showbizpsy.

"It used to be a tough neighborhood and it still is a bit rough round the edges, but the influx of big stars is changing it dramatically. You see Keira wandering around, often wearing a hat to hide her features. She still gets recognized, but no one hassles her," a source said.

Knightley started dating Righton last year after being introduced by mutual friend Alexa Chung.
