Kim Kardashian's fiance Kris Humphries makes her "really happy".

The reality TV star will marry Kris Humphries on August 20 and Kim's close pal Ciara thinks the pair are perfect for each other and says she is relieved her friend found the perfect man.

She told America's OK! Magazine: "I am going. I'm just happy to be able to support her in this moment and to see her do it. It's going to be really fun.

"This is really a beautiful time and especially when you know the journey of your friends. This is one of the biggest moments of our lives as women. She found someone that makes her really happy and that's what's really important."

The couple are planning a lavish ceremony and Kim, 30, recently revealed close family friend Vera Wang, will make her wedding gown.

She wrote on her blog: "I am so excited to reveal that Vera Wang is my wedding dress designer. Vera has been a close family friend for a long time and we had talked about this moment for years, so when it came to picking my wedding dress designer she was the first person I thought of. No one designs gowns the way she does!

"I know that Vera can make my dream come true and create the most perfect gown for my special day."
