Kylie Kelce is celebrating her sixth wedding anniversary with husband Jason

Kylie Kelce is celebrating her sixth wedding anniversary with her husband, Jason, as she also shared a sweet photo of her dog as flower girl from that day on social media.

On Sunday, April 14, the 32-year-old mother of three took to Instagram to share a black-and-white photo of herself and Jason, 36, posing hand-in-hand as a newlywed couple in professional photos taken during their ceremony on her story.

The date of their wedding anniversary, ‘4.14.18’, was used as the caption for Kylie’s original post, which was made a day after she and Jason became newlyweds.

“Six years since we said ‘I do,'” she wrote in a message above the snap.

Another photo on Kylie’s Story shows the couple’s beloved late dog Winnie walking with a garland around her neck at the exchange of vows, which took place outdoors.

Winne, who Kylie adopted in 2017, died in March. She was a furry flower girl at the wedding

“… with the cutest flower girl ever,” Kylie said of Winnie in another caption. The photo was shared after she announced the sad death of her Irish Wolfhound, who Kylie adopted in May 2017, in March.

Kylie and Jason got hitched at the Logan Hotel in Philadelphia six years ago, two months after Jason became a Super Bowl champion with the Eagles.

The couple share three daughters – Bennett, 11 months, Elliotte, 3, and Wyatt, 4.

Last month, Kylie revealed to PEOPLE that she initially felt ‘intimidated’ walking down the aisle in front of guests at her wedding. But that fear disappeared as soon as she saw her future husband.

Kylie recalled her favorite wedding memory as she walked down the aisle to Jason

“I personally know that my favorite wedding memory is when I was getting ready to walk down the aisle,” she recalled. ‘I was scared, not because I was going to get married, but because everyone would stare at me.

“As soon as our wedding planner opened the door and I could see Jason, it was like all the worries melted away. So I was like, “Oh, I’m just going to have to get to him. I can do it.”’

Kylie also said her second favorite wedding memory was when she got to sit at her boyfriend’s table with Jason.

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