Former UFC champion Jon Jones joins as partner for new Baton Rouge pizzeriaBATON ROUGE — Former UFC champion Jon Jones has joined the ownership team of a new Baton Rouge location of Prince St. Pizza, a New York City-born pizzeria expanding to Louisiana. Known for becoming the youngest UFC champion at 23, Jones held multiple titles during his tenure. The partnership comes ahead of the anticipated opening of the new Baton Rouge location in early fall. Prince St. Pizza, known for its Sicilian-style square pies and signature pepperoni-loaded slices, currently operates 18 pizzerias across the nation, mostly in California. Lawrence has built something special, and being even a small part of bringing this to Baton Rouge felt like an opportunity I wanted to be involved in from day one."
