The two major hotties, Lauren Conrad and Heidi Montag used to be absolutely inseparable when they were both starring on The Hills. They were the best of friends until 2007, when Heidi did something that no best friend should ever do.
She began dating Spencer Pratt (he is Lauren’s husband now, so you know how that turned out).
Things really got ugly from that point onwards and the two are not on speaking terms today.
