Selena Gomez thanked "Neon Lights" singer Demi Lovato for her support during her time in rehab, and reunited with her ex boyfriend Justin Bieber after returning to the stage in Texas. Selena Gomez only lasted two weeks out of the recommended 45 day-stay of rehab at the Dawn at the Meadows treatment facility in Arizona earlier this year. 

Selena Gomez's reps revealed back in January that the "Come and Get It" singer had attended two weeks of rehab, following a recommended 45 day-stay for alcohol, drug and prescription pill addiction, Hollywood Life reports

"I've done everything I could to the best of my ability," Selena wrote on Instagram, which was posted on Feb. 10. "Thank you for the unconditional love and cyber hugs. You inspire me."

Selena recently thanked her best friend Demi Lovato while making a speech on Feb. 27 at the unite4:humanity gala, for her support during the difficult time. Gomez was at the event accepting the Young Humanitarian Award for her extensive work with UNICEF.

"I want to thank Demi. Just the fact that we're here at 21 years old, and we've always talked about using our voice to help this generation. Sometimes I feel like we're the only ones holding the fort and I'm so thankful for you [inspiring] me every day," Selena said in her speech.

Demi also publicly attended rehab for her drug addiction, and was reportedly there supporting her BFF while she was seeking treatment.

E! News reports that Selena Gomez blew fans away at her first performance on the stage since going into rehab. The 21-year-old pop star performed at the 2014 BorderFest concert at the Hidalgo State Farm Arena in Texas on Saturday evening, marking her first show since her stint in rehab.

Meanwhile, Gomez was spotted with her ex boyfriend Justin Bieber and several other friends on Friday having breakfast together, E! News reports, leading to speculation that the two may have rekindled their friendship.

Let's hope those two weeks in rehab were enough for Selena to stay healthy and happy.
