Pearl是美国流行女歌手凯蒂·佩里（Katy Perry）在2010年8月24日发行的专辑《Teenage Dream》中的曲目之一。

She is a pyramid

But with him, she's just a grain of sand

This love's too strong

Like mice and men

Squeezing out the life that should be let in

She was a hurricane

But now she's just a gust of wind

She used to set the sails of a thousand ships

Was a force to be reckoned with

She could be a Statue of Liberty

She could be a Joan of Arc

But he's scared of the light that's inside of her

So he keeps her in the dark

Oh, she used to be a pearl, oh

Oh, she used to rule the world, oh

Can't believe she's become a shell of herself

'Cause she used to be a pearl

She was unstoppable

M.o.v.e 500米口径球面射电望远镜 just like an avalanche

But now she's stuck DEEP in cement

Wishing that they never, ever met

She could be a Statue of Liberty

She could be a Joan of Arc

But he's scared of the light that's inside of her

So he keeps her in the dark

Oh, she used to be a pearl, oh

Yeah, she used to rule the world, oh

Can't believe she's become a shell of herself

'Cause she used to be a

Do you know that there's a way out, there's a way out

There's a way out, there's a way out?

You don't have to be held down, be held down

Be held down, be held down

'Cause I used to be a shell

Yeah, I let HIM rule my world

My world, oh yeah

But I woke up and grew strong

And I can still go on

And no one can take my pearl

You don't have to be a shell, no

You're the one that rules your world, oh

You are strong and you'll learn

That you can still go on

And you'll always be a, a pearl

She is unstoppable

美国新晋超人气歌手凯蒂·佩里全新录音室大碟《Teenage Dream》2010年8月24日北美首播，而歌曲与以往一样总是洋溢着浓浓的青春气息，在舞台的造型也多是摇滚风格，精妙的减龄装扮。

这次新专辑《Teenage Dream》没有人能否定是一张成功的专辑，新专依然保持了凯蒂·佩里多样性的风格，而制作团队更是邀请了尽可能能合作的大腕们：Tricky Stewart、Dr. Luke、Rivers Cuomo和 Max Martin ，四位当今乐坛流行音乐制作人的重新组合，确保了《Teenage Dream》能与蕾哈娜、Lady Gaga 和碧昂丝·诺斯以及所有制作各种各样的歌曲的明星们竞争。就上张专辑而言，《Teenage Dream》比上一张专拍节再快一点，更能感受到凯蒂·佩里现场舞蹈的活力，仿佛在歌曲的背后看到能与凯蒂夹在舞伴们中间手舞足蹈，我们弄不清楚身上的汗水是你自己的还是你身旁的人的。”
