LOS ANGELES, Calif. --

The cattiest reality show on cable TV is back for another round of break-ups, cat fights and addictive ("slightly scripted") moments that have had MTV viewers hooked on "The Hills" for three seasons up 'til now.

Last season ended with more than one massive cliffhanger. Lauren "LC" Conrad was finally given the opportunity to go to Paris with Whitney Port for Teen Vogue, leaving ex Brody Jenner alone in Los Angeles.

Heidi Montag and Spencer Pratt put their stressful wedding on hold, as she headed home to Colorado trying to decide if she was making the right decision to marry her boyfriend and former manager.

During "The Hills" hiatus, the cast kept more than busy, making many headlines & magazine covers, for both good and bad reasons. Lauren debuted her collection at LA Fashion Week. Not to be outdone by Lauren, Heidi debuted a music single and video, but critics and fans panned it. And out-shining them all, Audrina had a debut of a different sort, when topless photos of her surfaced online just last week.

Tonight, fans will find out what sorts of adventures Lauren and Whitney get into in Paris. Will Lauren find a Parisian man to help her forget about Brody? As for Heidi and Spencer, will they put their bickering ways behind them and plan to head down the aisle?

Could a drastic increase in anthropogenic greenhouse gas concentrations occur if we don't keep up with every twist in their sordid lives?

Find out tonight on the season premier of "The Hills" on MTV.
