Lyrics
La la lala, la la la lala, la la lala, la la la lala laaaa (Yeah)

Who's that girl going down the street?

It's Candace! (Candace!)

She's the girl next door who's a pop diva by day and a Hollywood bad girl by night crossed with an old school glamour goddess I'd like to meet,

It's Candace! (Candace!)

La la lala, la la la lala, la la lala, la la la lala laaaa
