Heidi has obviously been thinking a lot about a Hills reunion recently, as she has even been dreaming about it in her sleep.
Earlier today, Heidi took to Twitter and name-checked the girls, along with Whitney Port, while revealing her bizarre dream to fans.
Considering she and Lauren don't speak anymore, tagging her into a tweet is quite a big step!
Heidi, who is married to her Hills co-star Spencer Pratt, said: "I had the funniest dream @LaurenConrad @AudrinaPatridge @whitneyEVEport and I were performing like the Spice Girls for our #HillsReunion!"
Now that would be..err..interesting!
There has been no talk of a reunion, but Heidi's tweet almost implies that one is in the works. One fan even replied: "WAIT, IS THERE A REUNION COMING UP?"
We hope so, don't you?!
