《Bad Liar》的中文歌詞如下：
I'm not a perfect girl
我並不是個完美的女孩
But there's something in my head
但有些事情在我腦海里揮之不去
That won't let up and it's driving me mad
這些念頭揮之不去，讓我快要發瘋
And I don't know what it is
我不知道這是為什麼
But I'm a believer
但我依然深信不疑
And you can call me a liar
你可以說我撒謊
Or just a crazy girl that won't get out of your head
或者只是個瘋狂的女孩，她不會離開你的腦海
Chorus:
Bad liar, I'm a bad liar 我是個壞謊話精，我是個壞謊話精
My brain is talking but my mouth won't say what my heart knows
我心裡想什麼嘴上卻說不出來
But every night I dream about the same thing
但每晚我都會夢見同樣的事
And I can't fight it, it won't stop calling my name
我無法抗拒，它不停地呼喚著我的名字
Bad liar, I'm a bad liar 我是個壞謊話精，我是個壞謊話精
Now you're in my head and you won't get out
現在你進入我的腦海，再也無法出來
I want you more than I ever wanted anything before
我比你更想要你，以前我從未如此渴望過什麼
But it doesn't mean I should believe every word you say is true
但這並不意味著我每一句話都應相信你是真的說了的
I try to put you down, but my heart keeps lifting you up
我嘗試把你放下，但我的心卻把你捧起
Chorus:
Bad liar, I'm a bad liar 我是個壞謊話精，我是個壞謊話精
My brain is talking but my mouth won't say what my heart knows
我心裡想什麼嘴上卻說不出來
But every night I dream about the same thing
但每晚我都會夢見同樣的事
And I can't fight it, it won't stop calling my name
我無法抗拒，它不停地呼喚著我的名字
Bad liar, I'm a bad liar 我是個壞謊話精，我是個壞謊話精
You could be the truth or you could be a game I can't win
你可以是真實，也可以是一場我無法獲勝的遊戲
I don't know which one I should choose, so I might as well run with it
我不知道我應該選擇哪一個，所以不如隨它去吧
And if it's just a bad dream, then I might as well finish it off with a kiss goodnight
如果這只是一場美夢，那么我應該在晚安吻中醒來結束它
So tell me baby, are you real or are you just a bad liar?
所以告訴我寶貝，你是真實的嗎，還是只是一個壞謊話精？
Chorus: (repeat)
Bad liar, I'm a bad liar (repeat) 我是個壞謊話精，我是個壞謊話精（重複）
