Let's face it, the Duggar kids have a lot to choose from when it comes to their favorite sibling.
But for Jessa Duggar and her younger sister Jinger Duggar, there's a special bond that may just be a step above the rest.
In an exclusive sneak peek at Tuesday night's 19 Kids and Counting: All About Jessa, fans get a new perspective on a sisterly love that can't be ignored.
"They pray together. They talk a lot. They bounce a lot of ideas off each other," proud mama Michelle Duggar explains in the preview. "They are motivated people, both of them. They like to get a job done."
Jim Bob Duggar thinks the two are inseparable and love doing girly things as a pair.
"Jessa and Jinger love shopping together, they love cooking together, they love organizing together," he explains. "They love going on trips together. They just love being together."
So how did these two become attached at the hip? Age certainly plays a big factor. Born 412 days apart, the twosome finds themselves with plenty of similar interests.
"Jessa and I are definitely besties," a 14-year-old Jinger shares in a throwback interview. "I mean, just because we are closer in age and we both like to do the same things."
And while the two admit to having "totally different" personalities, their similarities far outweigh the differences.
"We work together very well," Jinger explains. "Jessa is more like a leader and I don't like to be the one in charge, like everything on my plate. I kind of just like to follow people."
19 Kids and Counting airs Tuesday nights at 9 p.m. only on TLC.
