The former Simple Life star then posted another photo bundle of pics of herself and Zylka, 32, in honor of their anniversary. "Happy Anniversary my love! Thank you for making me feel like a Disney princess every single day. You are my knight in shining armor and I have never felt so safe and secure," she wrote. "You have changed my life in so many ways and shown me what true love really is. You are my best friend, my other half and made me see that fairytales exist and dreams really do come true. I love you, baby."

It's been a big week for Hilton, who also came out with a new perfume, Rose Rush, and teased a new song, "Summer Reign." But it's her personal life that really seems to be taking off!

Hilton recently gushed to ET about how madly in love she is with Zylka. "[Being soulmates is] just being best friends and finally finding someone that I love and trust and know that I want to spend the rest of my life with," she said. "It's the best feeling in the world."
