Did 14-year-old singer Ali Lohan have a summer growth spurt?

Us Weekly reports in its latest issue, on newsstands now, that the young star of Living Lohan flaunted what looked like overnight curves at a Jonas Brothers concert in East Hampton, NY on August 9. Just three months earlier, a flatter Lohan hit Fuse for a taping of The Sauce in NYC.

Lindsay blogged about the incident last night saying:

i just had to share something that came up today and it made me feel a bit sick to my stomach. so, here's the visual... me and my friend Patrick walking into a store, and two paparazzi come up out of nowhere (like usual) and start throwing questions at me... one of them being, "Hey Lindsay, what do you have to say about people commenting on your sisters implants?" WOW!!!!!!!!!!!!!!!!!!!!!!!! my response simply was, "Did you really just ask me that? She is a 14 year old girl, and you are a pedophile!"
