Westlife - Unbreakable
Took my hands,touched my heart
Held me close,you were always there
By my side,night and day
Through it all,baby come what may
Swept away on a wave of emotion
Oh we're caught in the eye of the storm
And whenever you smile
I can hardly believe that you're mine
Believe that you're mine
This love is unbreakable
It's unmistakable
And each time I look in your eyes
I know why
This love is untouchable
A feeling my heart just can't deny
Each time I look in your eyes,oh baby
I know why
This love is unbreakable
Share the laughter,share the tears
We both know we'll go on from here
Cuz together,we are strong
In my arms,that's where you belong
I've been touched by the hands of an angel
I've been blessed by the power of love
And whenever you smile
I can hardly believe that you're mine
This love is unbreakable
It's unmistakable
Each time I look in your eyes
I know why
This love is untouchable
A feeling my heart just can't deny
Each time you whisper my name,oh baby
I know why
This love is unbreakable
Through fire and flame
When all this is over
Our love still remains
This love is unbreakable
It's unmistakable
Each time I look in your eyes
I know why
This love is untouchable
A feeling my heart just can't deny
Each time you whisper my name,oh baby
I know why
Cuz each time I look in your eyes,oh baby
I know why
This love is unbreakable
