Kristin Cavallari left the west coast to celebrate NYE in Miami with her latest boyfriend Nick Zano. Apparently the two had a steamy weekend together which included romantic dinners and skinny dipping. In fact, Kristin has no problem flaunting her new love in front of her ex, Brody Jenner. Kristin also declared a new year's resolution. She said, "My goal is to stop swearing... You can say I have a bit of a potty mouth." That's a good resolution, but I'm more interested to see if Kristin and Nick will last through the year.
