Sports Illustrated Swimsuit Issue regular Julie Henderson was spotted in a pink and purple bikini on Miami Beach Saturday, surely adding more heat to an already sizzling day.

The 27-year-old Houston, Texas, native smiled for cameras as she enjoyed her day.

Speaking of SI's annual swimwear extravaganza, editor M.J. Day has been posting several bikini shots of all the models for the forthcoming issue to her Instagram page. We assume Julie will be in the issue, but Day posted only teaser shots -- only bodies and no faces. So far we've picked out Kate Upton and Emily Ratajkowski (we think). See the pics here.
