When I'm 18 I'm gonna be famous 
Everybody in my school is gonna be jealous 
I'll be out shoppin' like there's no tomorrow 
Be sittin' with my friends in my fancy limo 
I'm gonna blast the music loud, 
party ‘til the neighbors complain about the sound 
I'm gonna go crazy 
Do what I want ‘cause I'm the kind of girl who wants to have 
Fun, fun, I wanna have fun, fun 

When it's summer and school is out, 
gonna drive my friends in the convertible around 
Paparazzi will want pictures of me 
‘cause they know how much they're worth since I'm a very big deal 
They catch me hangin' out, hangin' with some boys 
It ends up on the front page of the tabloids 
I give the press a story to write about 
and then they go and twist it, but I really had no doubt 

When I'm 18 I'm gonna be famous 
Everybody in my school is gonna be jealous 
I'll be out shoppin' like there's no tomorrow 
Be sittin' with my friends in my fancy limo 
I'm gonna blast the music loud, 
party ‘til the neighbors complain about the sound 
I'm gonna go crazy 
Do what I want ‘cause I'm the kind of girl who wants to have 
Fun, fun, I wanna have fun, fun, I'm gonna have fun 

I can't wait for this dream to become a reality 
I want people to see my special personality 
They'll say I'm bubbly, but lazy and just a little crazy 
They'll say I'm sweet and petite and a total treat 
I'll be livin' the life of a superstar 
Have people following me when I'm out in my car 

When I'm 18 I'm gonna be famous 
Everybody in my school is gonna be jealous 
I'll be out shoppin' like there's no tomorrow 
Be sittin' with my friends in my fancy limo 
I'm gonna blast the music loud, 
party ‘til the neighbors complain about the sound 
I'm gonna go crazy 
Do what I want ‘cause I'm the kind of girl who wants to have 
Fun, fun, I wanna have fun, fun, I'm gonna have 
Fun, fun, I wanna have fun, fun, I'm gonna have (Shout outs to Orange County) 
Fun, fun, I wanna have fun, fun, I'm gonna have (On the beach!) 
Fun, fun, I wanna have fun, fun, I'm gonna have (In the sand!) 
Fun, fun, I wanna have fun, fun, I'm gonna have fun (When I'm 18!) 
Fun, fun, I wanna have fun, fun, I'm gonna have 
Fun, fun, I wanna have fun, fun, I'm gonna have
