RAP - I DONT KNOW THIS PART-

you showed up and you looked so classy,
Made me think twice bout the way I was acting
and you were there from the start of it all
like a dream came to life now Im left in all
And stars shine but your light is the brightest
and love flies but your love is the highest
So sweetthat it drives me crazy
a summer like no ther you my LA baby.
