Kristin Cavallari was a vision in yellow -- a yellow bikini that is -- during a backyard pool party in Los Angeles Friday. Take a look at these great pictures on RadarOnline.com.
Kristin’s bikini of choice was a bright yellow lacey number, perfect for summer and her to-die-for figure.
Kristin has said she will probably not be returning to The Hills if the reality show is renewed for another season. Among other things, she wants to write a book. Paging Lauren Conrad!
