On this week's episode of "Who Do You Think You Are?" (Tues., Aug. 27 at 9 p.m. ET on TLC), Cindy Crawford finds out that her ancestors include Earls, Counts, Dukes and even a King of Italy ... because of course.

Watch our exclusive sneak peek, above, to see the 47-year-old former supermodel from DeKalb, Illinois, get shocked as she uncovers the impressive titles in her family tree.

Tracing back over 12 centuries, a scroll rolls out to reveal over 40 generations of her family, and there's something at the top that's even more impressive, more "august," than any King of Italy, according to the genealogist.

Watch and tell us: Who do you think it is? Do you find this show as fascinating as we do?

"Who Do You Think You Are?" airs Tuesdays at 9 p.m. ET on TLC.
