Picha: Part ya 'Bikini Showdown' ya Justin Bieber ilikuwa kumuumiza Selena Gomez!

Justin Bieber isn’t ready to get rid of his bad boy behavior quite yet. After just reuniting with good girl Selena Gomez, Justin is back on the party scene. 

The “Boyfriend” singer was spotted on a yacht in Miami partying with very hot ladies. These bikini-clad ladies socialized with a very shirtless Justin along with his friend Khalil Sharieff, 20.

Selena — Justin’s supposed love — was nowhere to be seen on the boat or in Miami. Justin has quite a knack for breaking her heart in a very public way, doesn’t he?

The past couple of weeks haven’t been too good to Selena. Justin’s reformed attitude has gone haywire and her besties Taylor Swift, 24, and Demi Lovato, 21, have turned away from her because of her relationship with Justin.

So will Selena be spending Independence Day alone? It kind of looks like it. (Sigh.) Selena better grab the tissues or book a flight to Miami because Justin’s former fling Chantel Jeffries is headed to Miami as well.
