《Sweetheart》的歌詞如下：
中文版：
你是我的甜蜜蜜，我的唯一
每時每刻都想你，想著你甜蜜的感覺
想和你一起走，手牽手走過每個路口
就算颳風下雨，我都不會猶豫
我的甜蜜蜜，你是我的唯一
就算天荒地老，我的心不會變
我會一直愛你，直到我們老去
我的甜蜜蜜，你是我的唯一
英文版：
You are my sweetheart, my only one
Every moment I think of you, the sweeter it gets
I want to walk with you, hand in hand, across every street
Even if it's raining, I won't hesitate
My sweetheart, you are my only one
Even if the sky falls and the earth crumbles, my heart won't change
I will love you forever, until we are old
My sweetheart, you are my only one
