《相愛穿梭千年》是由湖南衛視、天娛傳媒、CJ E&M三方共同出品打造的一檔周播欄目劇。該劇由井柏然、鄭爽領銜主演，講述了現代小演員林湘湘與志在維護正統的西漢士大夫公明一段亙古恆久的曠世奇戀。
劇情簡介
公元前16年，士大夫公明維護正統，反對廢黜許皇后，知己王莽及其王氏一族則支持趙飛燕封后，兩人反目成仇，分道揚鑣。公明受到王莽部下子修追殺，陷入絕境，意外憑藉侍女影月贈送的玉佩，穿越2000年時空來到了2015年，與出演許皇后一角的小演員林湘湘邂逅。公明醒悟，寫着“時移勢易，遇死則生”的玉佩能讓他絕死逢生，穿梭時空。以玉佩、戒指和紅繩爲媒介，公明和湘湘在數次的時空穿梭相處間互生情愫，情定彼此。但是在公明原本的時空裏，他還有刀光劍影的使命要奔赴，有史書中註定的結局要逆轉。公明一次次的返回兩千年前，希望改變時局。留在現代與湘湘相守一生，似乎只是一個太過美好的夢想。究竟最終，這段穿梭於2000年時空間的愛戀能否修成正果?

歌曲歌詞
Like A Star
Just like a star across my sky
好似流星劃過我的天空
Just like an angel off the page
你像書中走出的天使
You have appeared to my life
出現在我的生命中
Feel like I'll never be the same
從未有過這樣的感覺
Just like a song in my heart
就像心中的響起的歌聲
Just like oil on my hands
溫暖我的掌心
Oh I do love you
我真的愛你
Still I wonder why it is
始終不懂
I don't argue like this
with anyone but you
我爲何這樣在乎你
You do it all the time
blowing out my mind
讓我如此神魂顛倒
You've got this look I can't describle
難以抗拒你的容顏
You make me feel I'm alive
你讓我的生命綻放
When everything else is a fade
當一切老去
without a doubt you're on my side
我相信，你依舊在我身邊
Heaven has been away too long
天堂太遠
Can't find the words to write this song
愛在心頭口難開，只能用歌聲代替蒼白的言語
Oh your love
喔，你的愛
Still I wonder why it is
始終不懂
I don't argue like this
with anyone but you
我爲何這樣在乎你
You do it all the time
Blowing out my mind
讓我如此神魂顛倒
yeah~ da~ da~
Now I've come to understand the way it is
如今我終於明白一切
It's not the secret anymore
再不是祕密
Cause we've been through that before
以前的點點滴滴
From tonight I know that you're the only one
從今夜開始，我知道你是我的唯一
I've been confused and in the dark
也曾迷惑不解，也曾在黑暗中獨行
Now I understand
現在我終於明瞭
yeah~ooo~
I wonder why it is
I don't argue like this
with anyone but you
I wonder why it is
I won't let my guard down
for anyone but you
You do it all the time
Blowing out my mind
Just like a star across my sky
Just like an angel off the page
You have appeared to my life
Feel like I'll never be the same
Just like a song in my heart
Just like oil on my hand
