Jill Duggar has said that she and Derick Dillard are waiting until they're married to be physical with each other -- and that includes hugging and kissing.
However, they slipped a bit when Dillard arrived home from Nepal.
In this exclusive clip of tonight's episode of "19 Kids & Counting" on TLC, Duggar and her family went to the airport to greet Dillard. However, in their excitement, they ran toward each other, setting off an alarm in the process -- and gave each other a real hug.
"Bless their hearts, they just gave a big hug but I think intentions were to do a side hug," Michelle Duggar told the camera. "Needless to say, I'm sure they won't let that happen again."
Later, Duggar, in a joint interview with Dillard, called the frontal hug "messed up," though Dillard said he "enjoyed it."
After all, he explained, he had to be in Nepal by himself for two months after finally meeting Duggar in person.
"Longest months of my life," he said. "Looking back on it, it was a short time but I don't think we ever want to go that long in the future without seeing each other."
They won't have to: The couple is now engaged and getting married this summer.
