USA Network has ordered six more episodes of its breakout comedy-reality series Chrisley Knows Best, bringing its third season, now in production, to 18 episodes, which will air in two parts. Season 3 will premiere in the summer.

The reality family comedy follows the lives of Atlanta-based Todd Chrisley and his clan — including his wife, five children and two grandchildren. In the newly ordered episodes, the Chrisleys will leave the U.S. for the first time for a visit to London.

Chrisley Knows Best was among the Top 10 new unscripted shows on cable for 2014 in all key demos and total viewers. Season 2 hit series highs and averaged 1.24 million adults 18-49 (+31 % over Season 1), 1.24M adults 25-54 (+41% over Season 1), and 2.32M total viewers (+37% over Season 1) week-to-week per episode.

Chrisley Knows Best is produced by Maverick TV and All3Media America, with Adam Greener, Stephanie Bloch Chambers, Jen Perry Leamy, Jim Sayer, Eli Holzman and Stephen Lambert serving as executive producers. Annie Kate Pons serves as supervising producer.
