[Chorus: blackbear]
All my diamonds shine 'cause they really diamonds
Bad bitches in line, they be really tryin'
They ask me if I'm high, I say "Really, really"
Got money on my mind, I say "Really, really"
And I look like I've been ballin', 'cause I'm really ballin'
I won't apologize, I'm not really sorry
They ask me if I'm lyin', I say "Really, really"
I'm really out my mind, really, really
Really, really

[Verse 1: Mike Posner]
Make 'em believe, I made 'em believe
A lyrical song writer and he can sing
Bringing in money like raking in leaves
I was just trying to get paper to sneeze
Achoo! That was a blessing
She special to you, I don't look at her special (No)
Actually I treat her regular
Not being seen, we not making no spectacle
Pose out a verse then he gave her to bear
He gave her back and I don't ever care
It's my fuckin' brother, it's not even weird
Nobody can see you us, no not even mirrors
Passing through Gardere to holler at Glover
Shout out to Black, shout out to Cedric
Grey Monte Carlo, cocaine 911
Just hollered at Trav, I'm like the Reverend
My section ridiculous, watch where you steppin'
Pockets on indigent, can't be too careful
Steve like 'em tall and when they yellow
Broke and in college, fresh with low mileage
I like 'em black, pretty white teeth
Body unique, booty on fleek
Jhené Aiko, chewing her cheeks
Groceries, please, you know that was me, woo

[Chorus: blackbear]
All my diamonds shine 'cause they really diamonds
Bad bitches in line, they be really tryin'
They ask me if I'm high, I say "Really, really"
Got money on my mind, I say "Really, really"
And I look like I've been ballin', 'cause I'm really ballin'
I won't apologize, I'm not really sorry
They ask me if I'm lyin', I say "Really, really"
I'm really out my mind, really, really
Really, really

[Post-Chorus]
Really, really, really, really
Oh-oh-oh
Really, really, really, really
Oh-oh-oh

[Verse 2: Mike Posner]
Yeah
Oyster Perpetual, it's not a replica
Mustang GT in the streets, smoking vegetables
Trunk in the front, do it make me a elephant?
I really really put syrup in my beverages
Shopping in Beverly, check out my etiquette
Loving my swag, women tailor keep checking it
Carats, they glisten in all of my necklaces
Feeling myself, really thought it was evident

[Chorus: blackbear]
All my diamonds shine 'cause they really diamonds
Bad bitches in line, they be really tryin'
They ask me if I'm high, I say "Really, really"
Got money on my mind, I say "Really, really"
And I look like I've been ballin', 'cause I'm really ballin'
I won't apologize, I'm not really sorry
They ask me if I'm lyin', I say "Really, really"
I'm really out my mind, really, really
Really, really

[Post-Chorus]
Really, really, really, really
Oh-oh-oh
Really, really, really, really
Oh-oh-oh
