"Besides my family and friends, you have always been there for me in the good times and in the tough times. I can always count on you. And I want you to know that you can always count on me." She noted, "Thank you for your caring, your understanding, your loyalty and most importantly your love. Thank you, Thank you, Thank you. Always, Jennifer."
