Paris has previously described her sister and brother-in-law as the perfect couple, telling People: "They're so loyal and so in love. They're like a prince and princess. I think it's important to find someone you trust and love and spent the rest of your life.

"I think that's the meaning of life; to get married and have a family."

Auntie Paris was also responsible for throwing Nicky two lavish baby showers. During the first of the lavish affairs at the Hotel Bel Air, it was revealed that Nicky and James were expecting a baby girl. The now proud aunt congratulated her sister on Instagram with a picture from the big day. "My sister is literally the most beautiful fashionable pregnant woman I've even seen in my life! #Glowing #Gorgeous #MILF."

Nicky and James first met at the wedding of Petra and James Stunt in August 2011, with the heiress later saying it was love at first sight. James popped the question three years later during a romantic holiday to Lake Como in August 2014, presenting his wife-to-be with an incredible five-carat Asscher cut diamond ring.
