Just two months after Selena Gomez left rehab — where she’d sought help for problems fueled in part by an on-off relationship with Justin Bieber — sources confirm to In Touch that the starlet has been out drinking and partying — on multiple occasions.

After a fight with her mom and stepdad, Selena fled to the Sunset Tower Hotel, where the pop star lived for a week. There, eyewitnesses tell the mag that the former Disney star was seen with a drink in her hand almost daily. “She looked like she’d been at it for a while,” an onlooker tells In Touch. “Her lips were stained from the red wine she was drinking.”

Selena was spotted at the hotel's Tower Bar and Restaurant with a group of friends on St. Patrick’s Day, being loud and rambunctious. “They didn’t order food. They just kept ordering rounds of drinks and going out to smoke cigarettes,” a fellow patron exclusively tells In Touch. “They definitely seemed drunk.”

Selena continued her wild ways at a house party thrown by Oscar winner Jared Leto at his Hollywood Hills mansion on March 21. “The party was mostly models, stylists and young Hollywood types — basically the same people you would find in any of the clubs that night,” says an insider.

Selena's parents are concerned about her partying ways: “Her family is begging her to get back into rehab, and to stop talking to Justin,” a source close to Selena discloses.
