Kendall Martin is the most beautiful girl i have ever seen. she has gorgeous brown hair, and her hazel eyes will make you forget about time and all other problems.

Kendall Martin is the one person you think of all day, how pretty she is and how you want to spend the rest of your life with her. I love u Kendall Martin.
