Paris Hilton can't wait to meet her unborn niece and be the "best aunt" she can. The 35-year-old businesswoman is "so excited" for her sister Nicky Hilton Rothschild to give birth to her daughter - her first child with he husband James Rothschild - and has already bought the tot a host of gifts. Speaking to Prestige Hong Kong magazine, she said: "I can't begin to describe the feeling, I'm so excited and so thrilled for Nicky. She will be a wonderful mom and I want to be the best aunt I can be. I'm already shopping for my niece and can't wait to meet her soon." Paris recently threw a lavish baby shower for Nicky at The Towers at the Waldorf Astoria in New York at which she presented her younger 32-year-old sibling with a white and pink heart-shaped cake. The blonde beauty is single again after splitting from her millionaire boyfriend Thomas Gross. But rather than worry about finding another guy, Paris is totally focused on her DJ career and business interests such as her new perfume and a new line of cosmetics and is adamant she's never been happier. She said: "I've been very busy. I'm working on a new apparel line, a new cosmetics line and I have my fourth summer DJ residency starting soon at Amnesia in Ibiza. Then I have a new video game and my 22nd fragrance all coming out later this year. I love to be busy! "I see myself primarily as a businesswoman but also as a music artist, DJ and philanthropist. When I was little my parents and grandfather instilled a strong work ethic in me and encouraged me to pursue my dreams. I always knew that I wanted to have a global brand and to do more than one thing, so I really enjoy what I do and feel very lucky and fortunate."
