Selena Gomez really let loose on Saturday night, dancing on tables to Rihanna's "Work" while drinking at rooftop bar Reata in Fort Worth, TX. But everything's under control, she was just celebrating her cousin Priscilla DeLeon's engagement, and her love of life and, apparently, tequila.

How much the former Disney star has changed! What's next, Selena, body shots off a hot bartender's chest (please, please, please)?

Also, adding fuel to the rumor fire, Gomez supposedly spent the whole night flirting with a "hot mystery man" who was definitely not Justin Bieber in a disguise.
