We told you: people love a cat fight!

As Lauren Conrad grabbed lunch (and smiled for the camera, seen here) with Laguna Beach's Trey Phillips, she could be happy with the results her argument with Heidi Montag earned in the ratings department.

Across the board, the show averaging over 3.6 million viewers. Here are other details:

• The Hills was the highest rated program for the night among the 12-34 demographic across all of cable and within its 10-11pm time period.

• The Hills season three premiere hour was the highest rated telecast of the year-to-date for MTV, also making it the highest rated telecast of The Hills franchise.

• The season three premiere out-did season one's premiere by 20% and season two's premiere by 44%.

So, say what you want about Spencer Pratt, but the man can garner ratings.
