《i believe》是王力宏和陶喆共同演唱的一首歌曲，歌詞如下：
陶喆：
everytime i see your face
it's like another piece of my heart goes missing
when i'm with you
i don't know what to say
but i know i have to say something
王力宏：
i believe i can love you
i believe i can make it through
you're all i've been thinking about
so let me show you
合唱：
i believe in you
i believe in my baby
i believe in you
i believe it feels right
everytime i'm with you
you're all that i'm thinking about
so let me hold you
and see if it still feels right
陶喆：
and when we touch
i can feel your heartbeat
it's like our hearts connecting
two hearts beating together as one
this feeling i can't deny it
this is something that i mustn't lose it
王力宏：
so i'll be holding on tight baby let me show you how
with every beat of my heart for you baby baby believe me now
合唱：
i believe in you i believe in my baby now i can tell you the truth
cause this feeling inside yeah yeah yeah yeah won't let me be with someone else
so let me hold you and see if it still feels right yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah
