Dina, Lindsay Lohan Fight Back Over Ali's Botox Rumors

It has taken Ali Lohan’s family a few days to respond to rumors that she cosmetically altered her face but now the littlest Lohan's mom, Dina, is fighting back.

“They actually think I would let Ali get botox or surgery?” Dina asks me. “So beyond ridiculous. She grew 3 inches over the summer.”

New photos of Lindsay’s younger sister with a dramatically different look set off a media firestorm last week. The 17-year-old aspiring model's rep even had to issue a statement insisting that Ali's face was all natural.

“The speculation and rumors are nothing new to the Lohans,” a family friend tells me. “Remember the rumors that Lindsay had had breast implants when she was Ali’s age? At first the family was just going to ignore them but now they have had enough and are fighting back.”

Lindsay herself even took to twitter to defend her sister: "I love how haters pick on my sister yet every runway model is just as thin! My sister is gorgeous and I'm so proud of her and her career!!!!"

Ali recently signed a modeling deal with Next Models, one of the top agencies representing supermodels like Petra Nemcova and Molly Sims.
