Avril Lavigne's hit song "Girlfriend" may not be as original as we thought. The punk popster is facing a lawsuit by the members of a 1970s rock band who claim her hit song "Girlfriend" rips off one of their tunes.

Well, like Lavigne must've totally, like, had some older people helping her with the song because it was written way before she was even born.

Yahoo! News reports songwriters Tommy Dunbar and James Gangwer alleged in a lawsuit filed in U.S. District Court that Lavigne and her co-writers lifted their 1979 song "I Wanna Be Your Boyfriend," which was originally performed by new wave band The Rubinoos.

"We are not so naive as to chalk it up to some sort of cosmic coincidence," Dunbar said Thursday. "The lyric, the meter, the rhythm — they're identical."

The first court date has been set for Aug. 28 in Oakland.

A spokeswoman for Lavigne declined to comment.

I WANNA BE YOUR BOYFRIEND

Sitting here so close, together
So far we're just friends, but I'm wondering whether
I, am I just imagining
You, or do you really have a thing for me
Like I think I see when I see you smile
And the smile's for me, I wanna tell you...
Hey, You, I Wanna Be Your Boyfriend
Trying to say I wanna be your number one
Hey, You, I Wanna Be Your Boyfriend
Gonna make you love me before I'm done
Late at night when I, when I can't sleep
Picture in my mind, I see you and me
I, I'm telling you what I wanna be
You, you're saying you're in love with me
And oh, it feels so good in a dream
That I know in life it's just got to be
I wanna tell you......
(Chorus)
Bridge:
Gonna make you love me, yeah I'm
Gonna make you love me, yeah I'm
Gonna make you love me, before I'm done
(Solo)
I, am I just imagining
You, or do you really have a thing for me
Like I think I see when I see you smile
And the smile's for me, I wanna tell you...
Hey, You, I Wanna Be Your Boyfriend
Trying to say I wanna be your number one
Hey, You, I Wanna Be Your Boyfriend
Gonna make you love me, yeah I'm
Gonna make you love me, yeah I'm
Gonna make you love me before I'm done

Avril Lavigne's song "Girlfriend"

Hey! Hey! You! You!
I don't like your girlfriend!
No way No way!
I think you need a new one
Hey! Hey! You! You!
I could be your girlfriend
Hey! Hey! You! You!
I know that you like me
No way! No way!
No it's not a secret
Hey! Hey! You! You!
I want to be your girlfriend
You're so fine
I want you mine
You're so delicious
I think about you all the time
You're so addictive
Don't you know what I could do to make you feel alright?
Don't pretend I think you know I'm damn precious
And hell yeah
I'm the mother f**king princess
I can tell you like me too and you know I'm right
She's like so whatever
You could do so much better
I think we should get together now
And that's what everyone's talking about!
Hey! Hey! You! You!

No way! No way!
No it's not a secret
Hey! Hey! You! You!
I want to be your girlfriend
I can see the way, I see the way you look at me
And even when you look away I know you think of me
I know you talk about me all the time
again and again(and again and again and again)
So come over here, tell me what I want to hear
Better yet make your girlfriend disappear
I don't want to hear you say her name ever again
(And again and again and again!)
Cause, She's like so whatever
And you could do so much better
I think we should get together now
And that's what everyone's talking about!
Hey! Hey! You! You!
