不得不愛的英文版歌詞如下：
I can't help falling in love
It might sound strange to you
But I can't help it, I fell in love with you
Every time I see you, my heart skips a beat
Like a melody that I can't get out of my head
Everywhere I go, you're on my mind
Can't help it, gotta keep you in my sight
This kind of feeling, I've never known before
Gotta keep myself from going too far
Can't help it, I feel like I'm drowning in the tide
You are the only one, I can't deny
It might sound crazy to you
But I can't help it, I fell in love with you
You are the one who got away
You don't know how I cried all night
I miss you every single day
But now I gotta let you go my way
It might be hard to let you go
But I gotta make a choice for myself
Can't help it, gotta face the truth now, my dear
It might be a little late, but I hope you can hear me say...
I can't help falling in love with you.
