Oh my baby, my baby, she don't want me no more
Ever since she saw my brother walking from the store
She thinks the way he runs and plays is really cute now
He's not the smartest one, he doesn't have the know-how
She likes his blonde hair and she thinks he's bold
Yeah, he's her very favorite, very funny nine-year-old

(Chorus)
Well my baby's in love with my little brother
She's all crazy about my little brother
Once she was mine, but now i better just forget her
Cause my baby's in love with my little brother

Now every time i see him, well he looks so glad
How could he be so happy, and me be so mad
What a pain in the butt to be only nine
He stole my girl, she once was mine
But my girl can't get enough of his curly blonde hair
The only way i could get her back if i was a millionare

(Chorus)
Oh my baby's in love with my little brother
She's got a thing for my little brother
Tell me what can he do that I can't do better
Cause my baby's in love with, i said, i said, i said
My baby's in love with my little brother
Head over heels for my little brother
I can't believe it, she want's to remeet my mother
Cause my baby's in love with my little brother

I knew we were headed for disaster
When i heard her say he was the dating master
Now she's got a serious admoration
For the youngest, cutest, brand-spanking newest, member to our family's newest generation

Well i don't wear tanktops and i don't gel my hair
And i don't pretend to be a billionare
And i know i won't get alot of money and fame
But i know two can play at this kinda game
Yeah, well lets just see how ticked off he'll get
When i tell her, he likes Alanis Morrissett

(Chorus)
Oh my baby was in love with my little brother
She had a thing for my little brother
Once she was his, but now he doesn't matter
Cause my baby was in love with i said, i said, i said
My baby was in love with my little brother
Head over heels for my little brother
If she wants to leave him i guess i better let her
Cause my baby was in love with my little brother
