Justin Bieber's Lambo Girl Chantel Jeffries -- Walk of Shame

elena Gomez can pound sand.  Justin Bieber's new girl stuck by his side in Miami the night after his DUI arrest ... and emerged this morning for a pretty epic walk of shame.

As we reported, self-proclaimed model Chantel Jeffries was riding shotgun in Bieber's yellow Lamborghini when he was popped for DUI.

And clearly, it was more than just a random hookup ... Chantel crashed with Bieber in his rented Miami mansion just hours after he was released from the pokey.

Meanwhile, Selena was out on the town in L.A., smiling and signing autographs for fans.
