I don't know how to thank my fans enough for the love you have shown me over the years and always on my birthday. Today I have focused on smiling about all that I'm grateful for and reflecting on the last ten years of music and performances we have shared together. Thank you for continuing to inspire me to mold my fantasies into reality. Embrace your differences, celebrate who you are, it's in the unique parts of you that greatness hides. Don't be afraid to find it. Thank you for the Birthday Wishes. I [love] You.
