Kristin Cavallari was a knockout at the "Burlesque" premiere in Los Angeles yesterday.  She walked the red carpet in a jewled green dress that showed off her long, lean legs.

The "Hills" star's former co-stars are back in the news again.  Heidi Montag and Spencer Pratt have renewed their wedding vows.

The reality couple split earlier this year, and Montag filed for legal separation in July, citing irreconcilable differences. They reconciled in September and Montag called off the legal action, while Pratt has since admitted the divorce proceedings were staged in a bid to land them a new TV deal.

We don't care about Heidi and Spencer. We want to see Kristin in the spotlight!
