There's a reason they call Paris the "City of Love" — just ask Kourtney Kardashian and Scott Disick!

On Monday, Nov. 12, the couple of six years took a romantic stroll through the French metropolis, where they're filming scenes for the E! reality show Kourtney & Kim Take Miami.

Touring the city with their 2-year-old son, Mason, the affectionate twosome proved their devotion to one another by adding their names to the Pont Des Arts bridge, where couples "lock up" their love by writing on a padlock, attaching it to the fence, and throwing the key into the river below.

Kardashian, 33 — chic as ever in a fur-lined black coat and black lace-up boots — used a black Sharpie to decorate a lock with her name and Disick's name before fixing it to the side of the bridge along with the thousands of other locks. Disick, 29, then tossed the key into the water, saying, "I think it's forever now, baby!"

Indeed, the future looks bright for the reality stars, who also have a 4-month-old daughter, Penelope. Despite tabloid reports claiming that the two are at odds over parenting issues, Kardashian says they've never been closer or more in sync.

"Scott is a great dad and is very connected to both of our children," she revealed in the Nov. 12 issue of Us Weekly. "He and I are in a really good, happy place."

Disick, for his part, insists that family is his first priority. Once dubbed "douchelord" by Kourtney's sister Khloe, the restaurateur is now totally focused on spending time with his kids and longtime love.

"My son is my best friend," he told Us. "Having two kids is, like, you couldn't be more legit. It's the real deal: Kourtney and I are Mom and Dad."

"Penelope is beautiful," he added. "I mean, my son is my world and my daughter is my new world. It's pretty unbelievable starting another chapter in your life."
