This week marks the anniversary of the controversial bikini. Controversial because of the debate over who created the two-piece swimsuit. Some say the bikini debut on June 3, 1946, when the first one was put on display in Paris and created by Louis Reard, a French designer. History also has couturier Jacques Heim as the inventor of the bikini. And even though claims have been made about the bikini debuting June 3, 1946, history also states the now-iconic swimsuit debuted on July 5, 1946, during a poolside fashion show in Paris. You know what, none of that mattered to former HGTV star Joanna Gaines as she rocked a two-piece bikini in Mexico while on her own 18th wedding anniversary with husband Chip.

Designer and entrepreneur and Fixer Upper star Joanna Gaines, 43, looked stunning in a Gingham bikini as she falls backward into a private pool.

The couple was in Mexico on a much-needed vacation and anniversary getaway.

The dynamic duo spent quality time together which included dinners together, shopping and sightseeing.
