Today Show host Kathie Lee Gifford revealed that she has been informed of the date, stating that she will be certain to attend the high-profile ceremony, according to PopEater.
"I've been told a particular date," Gifford said. "Darn right [husband Frank Gifford and I] are going to that wedding."
Meanwhile, a source told the website that the wedding has been set for some time in August.
"The date that close friends of the family are being given is toward the beginning of August," the source said. "They are looking at private estates in Los Angeles, since the location will make it much easier for guest flying in to attend."
Kardashian recently revealed that she is happy that her engagement to NBA star Kris Humphries has taken the pressure to get married off her older sister Kourtney, claiming that Kourtney is in no hurry to wed.
The 30-year-old socialite announced her engagement to Humphries in May, confessing that she had not expected a proposal.
