Kim Kardashian opted for a rather low-key look as she paid a visit to plastic surgeon Dr Diamond's office in Beverly Hills.The TV star, 42, was snapped sporting a rare makeup-free face as she arrived wearing a black hoodie and carrying a Louis Vuitton Limited Edition Silver Monogram Miroir Speedy 35 bag, which brought some of her usual glam to the ensemble. It's unclear exactly why Kim was visiting Dr Diamond on this occasion, but she is known to be a fan of his 'vampire facials' in which the skin is punctured, with the blood then being used within the facial. The Kardashian-Jenners are usually tight-lipped about what surgery they've undergone, although Kylie Jenner recently left fans shocked after admitting to having undergone a breast augmentation when she was 19 - something she had previously denied.
