Guess you can say Heidi Klum's show has really taken "auf." (Sorry.) Its fourth kickoff now ranks as Bravo's highest-rated season premiere of anything ever - in both total viewers and the 18-49 demo. Compared to Season 3, this week's season-opener was up 24 percent in 18-49-year-olds (for a total of nearly two million) and 20 percent in viewers of any old age (almost three million). Natch, the hour also won its time slot. - Ben Katner
