Selena Gomez has thanked her fans for their support.

The 21-year-old singer has spoken out for the first time since it was revealed she spent two weeks in rehab last month, and she has praised her supporters for ''inspiring'' her.

She wrote in an Instagram post: ''I've done everything I could to the best of my ability. Thank you for the unconditional love and cyber hugs. You inspire me.''

It has been claimed the 'Come & Get It' hitmaker sought help as she was ''burnt out'', while it has also been suggested her partying was getting out of control.

Selena - whose on/off relationship with Justin Bieber is said to have contributed to her problems - reportedly left rehab four weeks early as she felt two weeks at The Meadows clinic in Arizona was enough to get her back on track.

Following her treatment, the 'Spring Breakers' star - who cancelled a planned tour of Australia this month - is said to be doing ''so well'' and is now focused on returning to work and has been reading lots of scripts and attending casting calls in a bid to move forward.
