根據公開資料，《松任谷由實口紅的傳言》的歌詞作者不是松任谷由實，這首歌歌詞如下：
I heard a rumor about a red lipstick
It's a mystery to me
Maybe I'll find out one day
But until then, I'll keep on singing
So don't tell anyone
It's a secret
But I'm looking for something
I don't want anyone to know
I want to find my own way
It's a secret, I won't tell anyone
But I want to wear the red lipstick
Even if I look a bit crazy
I don't care
I want to be beautiful like a dream
Sometimes I feel lost in this world
And I feel like I don't belong here
But I won't give up easily
I want to find my own way
So don't tell anyone
It's a secret
But I'm looking for something
I don't want anyone to know
I want to find my own way
Maybe one day, I'll wear the red lipstick
With confidence and pride
I don't care what anyone thinks of me
I want to be beautiful like a dream
