Oh oh oh oh oh oh
Oh oh oh oh oh
Yeah I'm feeling good
Got my head up high
Nothing can bring me down
Tonight
Might be lonely all night
But I'll be just fine
Drinking champagne
Smiling like a million bucks
On your way
Just know you all mean so much to me
Gonna wear my crown til the cows come home
Yeah I'm feeling so happy
On my own medication
Take two happy pills
And call the midwife
'Cause I'm feeling so good
I'm gonna have a baby
And it's all because of you
Yeah it's all because of you
Oh oh oh oh oh oh
Oh oh oh oh oh
You're my inspiration
My medicine too
So let's get this party started
Now we're done
So I'm taking two happy pills for me and you
Oh yeah, you and me baby no need for two, two, two, two
I ain't feeling down one more day
Oh yeah, cause you and me we're happy together, together, together
Yeah I'm feeling good, yeah I'm feeling so good.
