'Vanderpump Rules' Jax Taylor -- Blabs About Hawaiian Sunglasses Arrest (VIDEO)

Jax Taylor from "Vanderpump Rules" should exercise his right to remain silent, because he's a little too loose lipped for his own good following his arrest in Hawaii.

Our photog spotted the reality star with co-star Kristen Doute, who tried to get him to shut up, to no avail. Jax suggests he did not steal from the sunglasses store last month, but the surveillance video seems to tell a very different story.

Jax was arrested for felony theft ... expensive shades.
