Paris Hilton thought her sister's wedding was "perfect".
The 34-year-old heiress was bridesmaid when Nicky Hilton and James Rothschild tied the knot in London's Kensington Palace last month and she felt the big day was a "fairytale" that she was proud to be a part of.
She said: "It was fabulous. It was the first wedding in our family, Nicky being the first of the our siblings to get married.
"Seeing my sister in her wedding gown, knowing she was so happy and so in love, was amazing. We all had a great time and are really happy to have a new member of the family.
"Nicky's wedding was definitely a fairytale. Every little detail was perfect."
And Paris - who is dating Swiss businessman Thomas Gross - was particularly moved when the couple exchanged their vows.
She added to HELLO! magazine: "It was very moving when they said their vows. The beginning of a life together, a celebration of love, commitments, friendship and loyalty. And that has a special meaning in our family.
"My parents have been together for 35 years, which is unusual these days. I hope we follow that tradition, as we all start to marry."
