Selena in Justin's tatted arms after REUNITED!

And after stirring the pot, Justin Bieber took to Instagram to once again profess his love to the 21-year-old singer in a collaborative and sexual dance routine.

Perhaps trying to show that the lovestruck stars have made mistakes but forgive each other - and suggesting that the world should as well - the Believe Hitmaker shared two clips of the pair performing a play-by-play to the lyrics of John Legend's song Ordinary People, though he later appeared to delete them.
