I wondered when my 13 year old son would discover girls.. this found on his FB answers the question. Here is one of my ultimate favorite celebrity Babe Billie Piper! ( Cencored by Dad) Same with Rihanna and Alyssa Milano. I freaking love Kat Dennings. She is so Nerdy and so cool so beautiful and seem like a chill person to hang with showing appreciation to her. Kat Dennings? I must talk to the boy!
