So, Ali’s not the catty one?

There are “Mean Girls,” and then there are mean girls – like two of Ali Lohan’s former classmates, who made a nasty video about her and then posted it on the Internet.

The 14-year-old calls herself a “nice girl, who wants to be friends with everybody.”

You just don’t want to mess with the Lohans, she says, because then there may be trouble.

The younger sister of You-Know-Who, and their mom, Dina, are at the center of “Living Lohan,” which chronicles Ali’s experience recording a CD (the finale airs Sunday on E!).

She talked by phone from her North Merrick, N.Y., home, where the kitchen decoration includes a sign that says: “If it has tires or testicles, it’s gonna give you trouble.”

Q. Why did you and your mom decide to do the show?

A. The tabloids were saying so many bad things about my family, and we wanted to respond. We wanted to show people that we’re a normal family.

Q. What’s the most important thing she’s taught you?

A. The same advice I get from my sister, which is to keep your head high and follow your dream. Lindsay has told me, “Don’t get caught up in what the tabloids say, because it will bring negative energy.”

Q. Lindsay gets hounded 24/7 by paparazzi. Don’t you worry you’ll get the same ride?

A. I know what to do and what not to do. I’ve been following in Lindsay’s footsteps forever, so I definitely have a bigger advantage, and I thank her for that.

Q. What’s the most absurd thing that’s been published about you?

A. That I got a nose job. I’m 14. That would never happen. Besides, everyone in my family has the same nose … Don’t be saying I got a nose job.

Q. You’re home-schooled now. What was it like for you in public school?

A. You know, there was a friend “situation.” A couple of girls in school made up a video about me and put it on YouTube. It was disgusting, and they got suspended for it. … But now my show came out, and they know about my single, so they’re all kissing my butt.

Q. You’re in a movie this fall, “Mostly Ghostly,” based on the R.L. Stine books. In five years, will you be a musician or a movie star?

A. Probably, hopefully, a successful musician. … I’ll probably still be in New York. But I love L.A. The weather’s amazing and it would be awesome to be with my sister every day.
