What goes on in Vegas most certainly will NOT stay in Vegas here!
Watch it go down (below)!!!
Gurl knows how to mark her territory!
Before a full-scale panic attack set in, we realized J Biebs was shooting his new music video for Boyfriend, and the other chica was just a actress starring in the video with him.
No cheating here! Justin's real lady love was standing behind the cameras watching the whole time!
As soon as the cameras shut off Selena didn't hesitate to show everyone on set who JB really belonged to. The second he walked off set momma jumped on her man (literally), and gave the cameras a show of some real PDA!
See more picks of Selena re-claiming her Boyfriend (below)! Young lurve!!!
