The 37-year-old DJ and socialite says the couple have a joint skincare regimen, which they always do together every single night.

She said: "Chris has been using all of the formulations since we began development. He loves the line. I wanted to make [a range] for both men and women. At night before we go to bed, we have our skincare regimen and do it together!"

And 'The Simple Life' star - who got engaged to the 'Leftovers' star over Christmas - feels skincare is a very important part of her life and thus why she wanted to create her own line, including an anti-aging line called ProD.N.A.

She added to the New York Post's Page Six column: "After years of trying everything out there, I decided to look into creating my own line with all the ingredients that have worked to keep my skin healthy and looking great. I have always been into skincare and being all natural, so I wanted to create the perfect skincare line for anti-aging. So many young girls are turning to cosmetic surgeries and invasive procedures, at an even younger age than before, and I want to help show them that there is a better way and it is possible to stay looking young and radiant without all of that."

Meanwhile, Paris previously feels "very lucky" to be marrying her "best friend".

She gushed: "It's very rare to find such an amazing man, I feel s lucky. One thing is life that I think is most priceless is loyalty, and honesty, and Chris is just my best friend. He's everything to me and I've never been happier in my life."
