Lisa Wilkinson revealed to Confidential on Sunday, "I have not been invited."
There have been reports that despite 10 years on the news desk together, Stefanovic and Wilkinson share a strictly professional relationship.
The 58-year-old Project host added, "There are elements of Today which I do miss but I am so focused on my new life and the new challenges which I have."
Wilkinson sensationally quit Today last November following a pay disparity dispute. It's believed Karl, 44, was reportedly earning $2million - almost double her salary.
Interestingly, Karl did not attend the festivities when Lisa renewed her vows to husband Pete FitzSimons last year.
Meanwhile, over the weekend, Yarbrough enjoyed a "boisterous hens party" with her girlfriends at Crown Towers, the Sydney Morning Herald reports.
According to the population, the Mara & Mine designer was joined by chicken heiress Tamie Ingham and a group of female friends.
The 33-year-old and her posse stayed at the Crown's $11,500-a-night presidential suite.
The presidential suite comes with a 24 hour butler service, a private elevator and champagne.
The Sydney Morning Herald reports that members of the group of hens were heard shouting, "This is Karl Stefanovic's fiancée" at "random guests" as they "made their way through the hotel".
According to a Sydney Morning Herald report, Karl's children from his first marriage to Cassandra Thorburn, Jackson, 19, Ava, 13 and River, 13, will travel to Mexico with Karl and Jasmine.
