Let’s hope that what happens in Vegas, truly stays there…

Everyone’s least favorite celebrity couple, Selena Gomez and Justin Bieber, cozied up together on a Las Vegas getaway this past weekend. The couple shacked up at the Hard Rock Hotel & Casino, where Bieber rented a three-bedroom, penthouse suite with a private pool.

The “Boyfriend” singer traveled to Vegas to support boxing champ Floyd Mayweather Jr. in his fight against Argentine Marco Maidana at the MGM Grand Gardens Arena.

Gomez, 22, took some time away from her boyfriend to relax in the pool with her girlfriends — including Vine personality Liane V.

Liane posted a picture with Gomez and two unnamed chicas chilling poolside and soaking up the sun in their private pool.

Later, Bieber, Selena and his entourage hung out with French Montana, Diane Kruger, Joshua Jackson, WIll Smith, Joe Jonas and Alex Pettyfer at a pre-party for the boxing match on Saturday. Bieber posted a picture with a brunette beauty (believed to be Gomez) on theiry way to the match. “At the Hard Rock Hotel LV pool before heading over to see the Champ,” he wrote.
