Jill Duggar and Derick Dillard are back near the altar—as guests! The newlyweds got dressed up in their best formal attire to attend a friend's wedding on Saturday, Aug. 2.

"Getting ready for our friend's wedding in Knoxville, TN!" Arkansas resident Duggar, 23, wrote via Instagram. "Congrats Madison and Madelyn! #derickdillard #jillmdillard #wedding."

The 19 Kids and Counting star and Dillard, 25, posed together in what appeared to be both the ceremony and reception room. Duggar wore a knee-length black dress and Dillard wore a tan suit.

The couple—who said "I do" themselves in June—documented their road trip with another photo the following day. "Road trip with some of our friends @thebatesfam @lawbates!" Duggar captioned. The TLC star sat in the front seat as she and her beau wore matching salmon-colored shirts.
