ROME – Kim Kardashian is living her best single life. The 40-year-old makeup mogul was spotted hitting the famous Colosseum on Tuesday before she joined her friends for lunch. For her day out, the KUWTK star slipped into a white, low-cut, long-sleeve bodysuit tucked into blue high-waisted shorts. The SKIMS founder paired her look with blue sunglasses and a pink-and-blue choker necklace. The Roman holiday comes as Kim’s first after filing a divorce from husband Kanye West.
