We’ve seen a lot of celebrity Hilary Duff on the set of “Gossip Girl” over the past few weeks and I for one am not complaining. I think Hilary has put on a few pounds over the past year, but she wears it quite well. The expansion of those curves have transformed the 21 year old Hilary Duff from cute to downright sexy! I think someone is becoming a woman! Hilary recently told the press that she’s a “huge fan” of “Gossip Girl.” Hilary also said of the show, “They called me and said come on and do a few episodes. I jumped at the chance. Everyone’s been really, really gracious to me and sweet to me.” Okay, that’s nice, but I think these pictures are way better!
