The heiress, 32, and her model beau, 22, hired bicycles and cycled around the pretty city of Amsterdam as they enjoyed a day out visiting the tourist attractions and sampling the country's cuisine.
Paris looked low-key chic in a tiger t'shirt, black trousers and black leather jacket, teamed with comfy trainers - perfect for a day's peddling!
A change from her usual LA life, Paris visited the famous Dam Square, before stopping for a bite to eat at The Pancake Bakery.
Tweeting her fans throughout the day, she wrote: "Yummy! My favourite thing to eat when I travel to Holland. The Dutch pancakes with strawberries & Nutella are amazing!"
She added that she "loved" the city and had "so much fun riding my bike around Amsterdam!"
