    18 years! What can I say?! You've worked so much for all this to happen! You deserve everything and more.. I hope you guys realize how many girls out there are happy for having you on their lifes.. And how happy you've been making me since the first time I saw you on tv.. Your music was (and still is) the soundtrack of my life.. So many memories, so many moments to treasure.. Specially this year, when I had the opportunity to meet you.. UNFORGETABLE!..
    Happy 18th anniversary!
