(Cover) - EN Showbiz - Kim Kardashian's mother Kris Jenner is said to be doing an "amazing" job planning her daughter's upcoming lavish wedding.

The reality star's younger sister Khlo told Us Weekly that her mother, who is also their manager, is being hands on with every detail of Kim's nuptials.

The 30-year-old is marrying NBA star Kris Humphries, 26, later this summer and Khlo says the plans are well under way and Kim should be very grateful for all the hard work being put in.

"I've seen how much my mom has been doing, and I don't know how my mom does it! Kim should be kissing the ground that my mom walks on. It's amazing," Khlo gushed.

But the 27-year-old, who married basketball player Lamar Odom after just a month of knowing each other, says she will be contributing by throwing her sister a traditional pre-wedding party.

"I am doing the bachelorette party. And that's going to be payback!" Khlo laughed.

She was referring to the party Kim threw for her before her own nuptials back in 2009 which Khlo called "very embarrassing".

"It was everything penis themed! Kim is not like that. She's very uncomfortable with that so we're going to embarrass her," she explained.

And Khlo says the event will be "royal wedding number two" adding that she "could only imagine Kim having the hugest wedding".

Kim and her fianc Kris became engaged in May after less than six months together. (C) Cover Media
