"I've done everything I could to the best of my ability. Thank you for the unconditional love and cyber hugs. You inspire me," Gomez wrote as the caption to a picture, in which she sports a big smile while holding a glass of what looks like red wine.
She is seen standing on a boat, reports contactmusic.com.
Gomez checked into the Dawn at the Meadows rehabilitation facility in Arizona last month, but for not any substance or alcohol issues.
