She's back!

Selena Gomez has completed treatment at the mental health facility where she's been since her September breakdown, and the first thing she did is head to Big Bear for a snowy vacation with her close pals.

The singer smiled for the cameras in snapshots posted by friends Connar Franklin and Bailee Madison, and it's nice to see her enjoying life after a rough couple of months.

The "Come & Get It" songstress is said to be in a much better mindset, too.

"Selena is definitely in a healthier place than she was a few months ago. It took lots of energy, focus and therapy to get over that particular hump in her life," a source dished to Us Weekly.

The brunette beauty was hospitalized twice in September shortly after Justin Bieber's secret courthouse marriage to Hailey Baldwin, and she's been battling health issues stemming from her lupus.

"[Selena] is feeling much better and looking forward to getting back to normalcy," another insider told People.

We admire her strength!
