They will both make separate appearances in the upcoming season. Lauren will be a guest judge on September 16th, which Kim K makes her appearance on October 21st.
But these two aren't the only big names added to the lineup for the season. Top Model fans can also expect to see Chanel Iman (Sept. 9), China Chow (Sept. 30), Josie Maran (Oct. 7) and Kirsty Hume (Oct. 28) as guest judges this season.
CW star Jessica Lowndes (90210) makes an appearance on Oct. 31. 90210's Adrianna won't be judging, but she does put the girls' "interviewing skills" to the test.
Will you tune in for the special appearances? Who would you love to see as guest judge on the panel?
