[Verse 1]
In the blink, of an eye
I feel the twist of a knife
In the flash of a smile
I see her heart on the prowl

[Pre-Chorus]
She knows what she's doin'
She knows I can tell
She'd love to see me lose it
But I tell myself

[Chorus]
No, don't get insecure
No, he ain't into her
She's playin' dirty, all flirty
From across the room
You might think she's a ten
But she don't count to him
'Cause girl, he's busy, gettin' dizzy
All around you
Don't waste a second, second guessin'
Get obsessed with her obsessin'
He's all yours, he ain't hers
She ain't worth gettin' insecure
(Oh, oh, oh)
[Verse 2]
Yeah, it ain't his fault
That when he talks, they all fall
I know they all want to take him
And the truth is, I can't blame them
'Cause he's tall dark and handsome
And still sweet as hell
In moments of weakness
I tell myself

[Chorus]
No, don't get insecure
No, he ain't into her
She's playin' dirty, all flirty
From across the room
You might think she's a ten
But she don't count to him
'Cause girl, he's busy, gettin' dizzy
All around you
Don't waste a second, second guessin'
Get obsessed with her obsessin'
He's all yours, he ain't hers
She ain't worth gettin' insecure
(Oh, oh, oh)
(Oh, oh, oh)
[Bridge]
Don't waste a second, second guessing
Get obsessed with her obsessing
Tell the voice inside my head

[Chorus]
No, don't get insecure
No, he ain't into her
She's playin' dirty, all flirty
From across the room
You might think she's a ten
But she don't count to him
'Cause girl, he's busy, gettin' dizzy
All around you
Don't waste a second, second guessin'
Get obsessed with her obsessin'
He's all yours, he ain't hers
She ain't worth gettin' insecure

[Outro]
(Oh, oh, oh)
(Don't waste a second, second guessing)
She ain't worth getting insecure
(Oh, oh, oh)
(Get obsessed with her obsessing)
