"Happy birthday my sweet Kenny!" Khloé wrote. "I love you for who you are and couldn't imagine a life without YOU. If anyone knows you like I do, they know how much of an amazing, kind, quirky, loving person you are and how much any one would dream to have you in their life. Some people aren't as lucky as us. Not everyone gets to have a sister and not everyone gets to have a love and bond that all us siblings have with one another. Blessed we are! We all celebrate you today and every day! Let your confidence continue to shine and never be anyone but yourself. You are perfect in every single way. I love you my sweet angel sister!"
