(Cover) - EN Showbiz - Kim Kardashian has invited a host of stars to her upcoming wedding, including Jennifer Lopez and Will Smith.

The TV star is due to marry her basketball player fianc Kris Humphries on August 20 and is planning a lavish ceremony. She wants to ensure famous faces attend the nuptials, and has sent out invitations to some of the biggest stars in the world.

"I know Jennifer Lopez and Justin Bieber are invited. Selena Gomez was invited, too but she is performing in New Jersey on the day of the wedding so she can't go," a source close to the star told RadarOnline.com.

"Will Smith and Jada will be guests, and of course Ryan Seacrest and Eva Longoria."

Other names believed to be on the guest list include Beyonc Knowles and her husband Jay-Z, as well as Kanye West.

Kim and Kris reportedly sent out their wedding invitations last week.

The couple will tie the knot in Montecito, California, and Kim will be wearing a bespoke Vera Wang gown. She is also releasing a special perfume to mark her big day called Love, and has reportedly ordered a ten-tiered wedding cake inspired by the wedding of Britain's Prince William and Catherine Middleton in April.

There are rumours the event may cost as much as $10 million, with speculation there will be several ceremonies in different places. (C) Cover Media
