Selena Gomez has thanked her fans for their support after revealing she spent time in a rehabilitation centre last month (Jan14).

The Come & Get It singer spent two weeks at a clinic in Arizona in January (14) seeking help from specialists for an unconfirmed issue.

On Tuesday (11Feb14), she addressed the issue for the first time since leaving the centre in a caption to a picture posted on her Instagram.com page, writing, "I've done everything I could to the best of my ability. Thank you for the unconditional love and cyber hugs. You inspire me."

In the snap, Gomez is seen standing on the bow of a boat on a lake, smiling and clutching a drink in her hand.

The former Disney star's rehab stay came shortly after she cancelled her Australian tour to "spend time on herself". Reports suggest she was treated for emotional issues.
