Kristin Cavallari, the reality TV star and entrepreneur, has shared new photographs of herself in a black string bikini while promoting her Uncommon Beauty skincare line. The 39-year-old is using the images to draw attention to her beauty brand as the summer season draws to a close.

The photos, taken from a promotional shoot, show Cavallari posing beside a sheer white curtain, continuing a run of publicity for her skincare venture. It follows earlier coverage of her fitness and beauty regime, which she has previously discussed in detail as part of her public-facing wellness brand.
