The year was a difficult year for Spears, who said earlier this month that she had taken some time off to focus on her self-care.
At the time of her contribution, People and other outlets reported that the star had checked in at a facility to seek "comprehensive wellness treatments."
In January, the singer stated that she had resigned from her career and residency in Las Vegas to help her father, who was involved in health issues.
She referred to her family's personal struggles in a message to her supporters earlier this week after she speculated on the pop star's absence in the limelight.
"My family has been through a lot of stress and anxiety lately, so I just needed time to get involved," Spears said on Instagram.
She added, "You may not know that about me, but I'm strong and stand for what I want!"
Spears asked for a bit of privacy to deal with all the harsh things that life puts in my way, claiming she would return "very soon".
Later, Spears released a video in which she trained herself, happily saying, "Who knew that stress would mean a big weight loss of 5 pounds, Yay for me."
