Nicky Hilton is "too busy" to plan her wedding.

The '365 Style' author told MailOnline: "I haven't planned a thing for my wedding. I've been too busy.

"I just got back from New York and as soon as I landed in LA my mom was there with all this wedding planning material. She had tear outs and inspiration boards and was ready to talk wedding planning. But I am not there yet, I have not made one plan so far."

The 'Real Housewives Of Beverly Hills' guest star added: "I haven't even picked a date or a wedding planner. I have been busy with my book. But I am excited for what lies ahead, and I am looking forward to putting it together."

The former model hasn't picked out her wedding dress yet.

She said: "I honestly don't know what type of dress I will wear. But I have seen some fun ideas for bridesmaid gowns, where the dresses are all the same design but different sherbet colours. I like that."

The blonde beauty got engaged to James during a romantic trip to Lake Como in Italy, but she doesn't know where they will exchange vows.

She said: "It's a little difficult because I am from Los Angeles and he is from London. So we will need to find a place that is good for both of us. It will be a lot of planning, but it will be fun."

Nicky's older sister Paris Hilton is looking forward to helping her organise the festivities.

The 33-year-old DJ said: "I have actually never helped anyone plan a wedding before. So this is all new to me."

She added: "I am so happy for them. I cried when I heard the news they were engaged. They are perfect for each other."
