USA Network lavished the good news on one of its shows, expanding the current season by 18 episodes and renewing the show for a sixth season. The show, “Chrisley Knows Best,” returns with new episodes on Tuesday, Sept. 12, with season five now stretching to 26 episodes.

The unscripted program also will have a new half-hour aftershow, “According to Chrisley,” which has an eight-episode order. The show will be hosted by Todd Chrisley.

Season five will wrap up with a two-part Christmas special.

“‘Chrisley Knows Best’ earned the series’ highest ratings to date during the first half of Season 5, averaging 3.2 million total viewers each week,” USA notes in its announcement, citing Nielsen L+7 figures. “When the show returns for the back half of Season 5 in September, Chase celebrates his 21st birthday, Nanny Faye pulls an epic prank on Todd, Savannah hosts a fashion show, and the family comes together as Julie awaits word on an all-too-familiar health diagnosis.”
