[Verse 1: Rihanna]
Gotta keep it on the down low
I'll never let my mama know
Only call him on my cell phone
Only see him after dark
I met him on the six train
Just the way he said my name
The brother had a lotta game
Had me open from the start
He scoops me up in his ride
Friday about a quarter to nine
So fly and so fine, and I'm so glad that he's all mine

[Chorus: Rihanna]
There's a thug in my life
How am I gonna tell my mama?
She's gonna say it ain't right, but he's so good to me
There's a thug in my life
And it's gonna cause crazy drama
I'm gonna see him tonight
I'm gonna give him everything

[Verse 2: Rihanna]
I know his crew's kinda shady
Sometimes it gets kinda crazy
But he treats me like a lady
Gives me everything I need
I don't care who's hating on me
'Cause every night, he's waiting on me
He's got mad personality, a side they never see
My friends tell me to slow down
But every time that he's around
My heart's on lock down
I feel love and I'm so proud
[Chorus: Rihanna]
There's a thug in my life
How am I gonna tell my mama?
She's gonna say it ain't right, but he's so good to me (So good to me)
There's a thug in my life
And it's gonna cause crazy drama
I'm gonna see him tonight
I'm gonna give him everything (Give him everything)

[Bridge: Rihanna]
Mama, don't worry, I'm not in a hurry
I won't disappoint you, I won't make you sorry
He's the one for me (He's all I ever need)
We'll be together from now 'til forever
I know it's the real thing
If you don't, whatever
And I know it's meant to be (I know it's meant to be, I know it's meant to be)

[Chorus: Rihanna]
There's a thug in my life
How am I gonna tell my mama? (How am I gonna tell my mama?)
She's gonna say it ain't right, but he's so good to me (Yeah)
There's a thug in my life
And it's gonna cause crazy drama
I'm gonna see him tonight
I'm gonna give him everything (Give him all of me)
[Outro: Rihanna]
Mama, don't worry, I'm not in a hurry (All of me)
I won't disappoint you, I won't make you sorry
