Lyrics:

Man, oh man
What in the world's got into me?
Losing control entirely
Head over heels exclusively
And my heart says this is something
My body says it too
And my head says, "Girl, accept it, this is you"
Mamma mia, mamma mia
You're a brand new part of me
How can I know this thing is real?
How can I feel the way I feel?
Mamma mia, mamma mia
When you do the things you do
Why did I fall in love so deep?
Why did my heart just skip a beat?
Na-na-na-na, na-na-na-na-na
Na-na-na-na, na-na-na-na
Na-na-na-na, na-na-na-na-na
Na-na-na-na, na-na-na-na
My, oh my
Stronger with every breath I take
More than a claim I wanna stake
You are the love I'm gonna make
And my heart says this is something
My body says it too
And my head says, "Girl, accept it, this is you"
Mamma mia, mamma mia
You're a brand new part of me
How can I know this thing is real?
How can I feel the way I feel?
Mamma mia, mamma mia
When you do the things you do
Why did I fall in love so deep?
Why did my heart just skip a beat?
Na-na-na-na, na-na-na-na-na
Na-na-na-na, na-na-na-na
Na-na-na-na, na-na-na-na-na
Na-na-na-na, na-na-na-na

Mamma mia, mamma mia
You're a brand new part of me
How can I know this thing is real?
How can I feel the way I feel?
Mamma mia, mamma mia
When you do the things you do
Why did I fall in love so deep?
Why did my heart just skip a beat?
Mamma mia, mamma mia
You're a brand new part of me
How can I know this thing is real?
