Song that was in season 2, finale.

Okay I'm going nuts right now, trying to find this song that was in season 2 finale.
It happened just before the concert, when Diddy buys them diamond necklaces.
It goes something like this
"Close your eyes, kisses all over you."
"Baby I know what you need so..."
I think the singer says bye bye or something like that. Pleeease it's driving me crazy.
Google is not helping me at all =( =( =(
