(Cover) - EN Showbiz - Khlo Kardashian is reluctant to help her sister Kim plan her wedding, claiming she will be a "bridezilla".

The TV star is engaged to basketball hunk Kris Humphries, after he proposed just six months into their romance. The couple are expected to tie the knot this summer and although Khlo is thrilled her older sister has found Mr. Right, she fears the beauty will soon become consumed with making sure her big day is perfect.

"I'm looking forward to being in the wedding," Khlo told People. "I don't want to help because Kim is going to be such a bridezilla! If I do one thing wrong, I'll be screwed! But I would love to be in the wedding. Kourtney and Kim were both my maids of honour, so she has to do the same for us."

Despite reports that Kim has decided to tie the knot in July or August, Khlo insists her 30-year-old sibling hasn't chosen a date yet. But while a time is yet to be set, Khlo is adamant the nuptials will be lavish and spectacular again comparing it to the April wedding of Britain's Duke and Duchess of Cambridge.

"People keep asking us, 'When is it?' She doesn't know," Khlo added. "But you know, Kim goes big. It's not going to be small. And I joke and I say it will be like the royal wedding, because she is just like that."

It was recently reported Kim is planning three wedding ceremonies in Los Angeles, New York and Miami. It was also claimed the star will spend $1 million on food, another $1 on floral arrangements and decorations and has set aside $1 million for her wedding gown and dresses for her bridesmaids.
