Kim Kardashian is "really calm" about her forthcoming wedding.

The reality TV star - who is set to marry basketball player Kris Humphries on August 20 - explained she is not worried about tying the knot with the professional basketball player because she had all of her "freak out moments" when they got engaged in May.

When asked whether she was nervous about the impending nuptials, she replied: "No, everyone says that you freak out, but I think that all of my freak out moments kind of happened at the beginning when we decided to get married this summer so that's like when you are like, 'Oh, when and where?' So once all of those decisions were made, like this week I have been really calm."

The 30-year-old socialite didn't realise just how much work goes in to organising a wedding, but the process has still been very enjoyable and exciting.

She added to America's OK! magazine: "I mean it's been so like everything that I have dreamed of and more. I had no idea how much work really goes into wedding planning and I really do have this newfound respect for Sharon Sacks, my wedding planner!"

Part of Kim's preparations for her big day has seen her plan to release a limited-edition perfume called Love by Kim Kardashian to coincide with the wedding.

Only 1,000 bottles have been produced, one of which she has taken to wear when she and Kris marry.
