Since its season one premiere on New Year's Day, "Bringing Up Bates" is the highest-rated series in UP's history. The reality series takes a fresh look on the ever-changing family dynamics of Gil and Kelly Jo Bates and their 19 kids, aged 2 to 25 and now two grandchildren (including Allie Jane!) with one more on the way.

The second season order for 13 episodes is currently in production on-location in Tennessee. In the all-new episodes, produced in association with Figure 8 Films ("19 Kids & Counting") viewers will see more of this tight-knit, uncommon Tennessee family where daily chaos is multiplied exponentially - but so are the joyful and poignant moments that life can bring.

Alyssa and John married on May 24, 2014 at Salem Baptist Church in Knoxville, TN, and the wedding and entire supersized Bates family were featured on the ABC late-night news program "Nightline." The Websters live in Clermont, FL. John works as a technician at the family's air conditioning business with his brothers. Before moving more than 625 miles from home and the world she grew up in, Alyssa was the Bates family chief shopper and 'chef,' as well as tax secretary for her father's tree service business.

Gil and Kelly Jo's first grandchild, Bradley Gilvin Bates, was born last October to eldest son Zach Bates (25) and his wife Whitney. Another Bates daughter, Erin and her husband Chad are expecting to give birth in June.

Keep an eye out for the happy event and more big news in the second season of 'Bringing up Bates' premiering on Thursday, june 4, exclusively on UP.
