The 36-year-old heiress said in a statement to PEOPLE, 'I am so excited to be engaged to the love of my life and my best friend. I have never felt so happy, safe and loved. He is perfect for me in every way and showed me that fairytales really do exist!'
Telling the story exclusively to PEOPLE, Paris revealed the pair were posing for photos on the mountain top in Aspen, Colorado, when 32-year-old Zylka got down on one knee.
Hilton says, 'I was so excited and surprised! I immediately said yes.'
The couple reportedly met at an Oscars party eight years ago, but have only been dating for two.
Their relationship was made public last February when Hilton posted a loved-up photo of the pair to her Instagram.
Zylka told PEOPLE, 'Paris is the most beautiful and incredible woman both inside and out. I feel like the luckiest man in the world to be marrying my dream girl. I can’t wait to spend the rest of our lives together.'
Congratulations to the couple!
