Lady Gaga treated herself to high-end fur coats in Russia before she rocked the house with the Rolling Stones at the Prudential Center this weekend. The “Poker Face” singer, who earned about $52 million last year, according to Forbes, and has clearly moved up from the meat dress, last week was spotted at the Helen Yarmak boutique in Moscow. Spies told us Gaga picked up a dark brown Barguzin Russian sable worth about $210,000, and wore the lush coat out of the store after she shopped. She also picked up a green-dyed silver fox coat worth about $19,600. We’re told Gaga was “charming, easygoing and absolutely delightful” to staffers during her visit.
