Getting all prettied up for a night on the town, Kristin Cavallari stepped out for the 2009 Jingle Ball at the Nokia Theatre in Los Angeles on Saturday night.

The “Hills” hottie smiled as she posed for pictures on the red carpet, proceeding to head inside to check out the fun-filled charitable festivities.

In related news, Miss Cavallari has been her usual busy self on her Twitter account, most recently posting messages relating to her sexy appearance.

She writes, “My friend says to me that I look like Alicja Bachleda – Curus. Colin Farrell’s girlfriend. I dont know whether that is a compliment or not.”

The 22-year-old added, “I want to grow old without face lifts. I want to have the courage to be loyal to the face I have made.”
