Instagram / @rachelzoe Naomi CampbellNaomi Campbell turned heads this week when she posed topless with friend and fellow model Kate Moss for the cover of Interview magazine’s Russian edition. The beauties were both sans top, but Campbell’s exposed assets covered up her friend’s bare chest. Rachel Zoe snapped this picture of a clothed Campbell and wrote, “Umm OMG Naomi Campbell in my collection on ‘The Face’…perfection.” @Instagram / @natashapolyNatasha PolyModels posing with baby animals are a deadly combination. Russian model Natasha Poly almost made our eyes explode with this one, in which she clutches two adorable cats while looking amazing. Instagram / @bfa_nycKaty Perry“The stunning @official_katyperry at the #Mikimoto celebration for the 8th annual @unicefusa #SnowflakeBall” is how the Billy Farrell Agency described this photo. The pop princess just signed a deal with beauty mogul Coty Inc. and is expected to expand her fragrance line with the company. Instagram / @pamelalovenycPamela LovePamela Love proves that good designers can think on their feet with this photo of some “sidewalk shoe switchin.” Earlier this month, Love and her unique accessory designs were the subject of a profile in Time. The article details Love’s early appreciation for innovation—for example, turning toothbrushes into bracelets. Instagram / @kevintachmanKevin Tachman“I hate my job,” writes Kevin Tachman (we hope) ironically. The photographer uploaded this photo of a nearly naked Calvin Klein model lounging in a conveniently exposed pose, showcasing a bevy of tanned abdominal muscles. Instagram / @edwardenninful Edward EnninfulHow many famous faces can you cram into one photo? Edward Enninful tried to answer that question when he uploaded this snapshot of a handful of fashionable friends at the W Love Hangover Ball in New York City. Instagram / @thecoveteur The Coveteur “Who needs a green juice in the morning when you can have a green dress?” wrote The Coveteur of this picture of a very green dress. And a bonus: if you get hungry, it turns into a skirt! Instagram / @derekblasberg Derek BlasbergDerek Blasberg snapped another shot from the W Love Hangover Ball, of some brightly dressed women strutting their stuff, and wrote of the picture: “They better work! My first and favorite Vogue ball. Yes, sweetie.” Instagram / @prabalgurung Prabal GurungWe wouldn’t mind being hugged and kissed by the gorgeous Zoe Saldana either. A favorite of Kate Middleton, designer Prabal Gurung posted this picture of himself with the lovely actress, and wrote, “However the highlight of my night? Surprise visit from my love…love her.” Clearly. Instagram / @stella_mccartneyStella McCartney“Stella and Rita Ora in our Spring Citrus Floral jacket at tonight’s #BFA,” wrote Stella McCartney (who apparently talks in third person) of this photo, which she posted on her Instagram account. The famed designer was named “Designer of the Year” at the British Fashion Awards on Tuesday in London. Instagram / @barrefaeli Bar RefaeliNow we know: even supermodels hate the dentist! While sitting in the dreaded chair, a fresh-faced Bar Refaeli uploaded this snapshot to her Instagram account and wrote, “Ouch!!” Even when she’s not modeling swimsuits, the active Instagram-er keeps busy. On Wednesday night, the Israeli beauty made an appearance on the German television show Million Dollar Shootingstar. Instagram / @caradelevingneCara DelevingneThe always beautiful and sometimes quirky Cara Delevingne showed off her eccentric side with this picture of a mystery woman wearing a giant faux head. “Guess who?” she wrote of the photo. We might have a guess.
