Last month, Kylie shared with PEOPLE her favorite memories from her wedding ahead of celebrating her sixth anniversary.

The mom of three said she first felt “terrified” before walking out in front of everyone at the ceremony, however when she saw her husband-to-be her fears melted away.

“I know personally my favorite wedding memory is when I was getting ready to walk down the aisle,” Kylie told PEOPLE. “I was terrified not because I was about to get married but because everyone was going to be staring at me.”

She continued, “As soon as our wedding planner opened the door and I could see Jason, it was as if all of the worries melted away,” she says. “So I was like, ‘Oh I just have to get to him. I can do that.’ ”

Kylie said her second favorite wedding memory was sitting at their sweetheart table, designated exclusively for the newlyweds at the reception.

It’s really the only time where you get to sit down and sort of catch up with each other because you’re running in opposite directions most of the day,” she told PEOPLE. “So we loved sitting down and having dinner just the two of us.”
