Selena Gomez took to Instagram on Monday to share her first post in four months.
"It's been a while since you have heard from me, but I wanted to wish everyone a happy new year and to thank you for your love and support," she captioned a series of black-and-white photos of herself.
"Last year was definitely a year of self-reflection, challenges and growth. It's always those challenges which show you who you are and what you are capable of overcoming."
The 26-year-old singer added, "Trust me, it's not easy, but I am proud of the person I am becoming and look forward to the year ahead. Love you all."
Gomez has been off the radar since entering treatment for mental health reasons.
