The Keeping Up With The Kardashians star will exchange vows with basketball player Kris Humphries in a lavish ceremony in Montecito, California.
Celebrities including Justin Bieber, Jennifer Lopez and Nicole Richie are all rumoured to be attending the nuptials, but talk show host DeGeneres was not invited.
In a post on her Twitter page on Thursday (18Aug11), she wrote, ""No invitation to Kim Kardashian's wedding yet. Worst Thing In The World.""
Kardashian noticed the message - and promptly reached out to the comedienne to ask her to attend her big day.
The brunette beauty declared, ""Of course u are invited!!!! COME!""
Meanwhile, Kardashian has enlisted the help of Dancing With The Stars professional Mark Ballas to help choreograph her moves for the reception.
Ballas' representative tells Access Hollywood, ""Yes, that is true - Mark has worked with Kim and Kris and is excited to share their big day with them.""
