Justin Bieber New Girlfriend? [PHOTOS]: The Biebs Already Over Selena Gomez Rebound Jordan Ozuna, Brings Mystery Girl Back to Vegas Hotel

19-year-old pop star Justin Bieber seems to really like the girls he finds in Las Vegas, Nevada. After splitting with Selena Gomez for good back in May of this year, everyone has been waiting to see who his rebound would be. Vegas waitress Jordan Ozuna (who happens to be married!) seemed to fill that void for Bieber, but after some early morning pictures of the Biebs and another mystery made the rounds this morning, it looks like Ozuna is out and this other Vegas girl is in! Well, at least for the night.

After his Friday night show in Las Vegas at the MGM Grand Garden Arena, Justin Bieber reportedly went to a private mansion party and then ended up getting back to his hotel around 6 a.m. The "Baby" singer was not alone, though, as photo evidence shows a young lady exiting Bieber's S.U.V. after Justin, and entered the hotel with the pop star.

People have already been criticizing the mystery girl, especially her outfit. Justin's hotel guest was dressed very casually in some jeans and a short shirt that showed off her stomach. Her full face of makeup suggested that she might have changed into the comfortable clothes sometime in the night, though her backpack and stuffed animal did not help the situation. It looks like Justin might be into the younger look these days!

It looks like Justin is having some fun as a single superstar. He was recently linked to Vegas waitress Jordan Ozuna, but apparently has moved on. News about Ozuna has been pouring in since the two were spotted together (of course), and there have been some interesting revelations.

A transplant from Maryland, Ozuna used to work for Hooters and still supports the popular chain on her Twitter account. Another very interesting fact is that she is technically married! Though the two are separated, Ozuna and her husband (who is serving in the Coast Guard) have yet to file for divorce.

Bieber has since left Vegas after the weekend, but do you think he will be heading back soon for another hook up? Do you think we will be hearing more about this mystery girl?
