Britney Spears revealed she's lost 5lbs due to 'stress,' following reports she voluntarily checked herself into a mental health facility last month.
As her 30 day program nears an end, the singer took to Instagram to show off her taut stomach as she worked out in a crop top and low-rise jogging bottoms.
37-year-old Britney gave fans a look at her energetic routine which involved lifting weights followed by sit ups on an exercise ball.
The Lucky songstress also bust out some of her old dance moves, as she writhed her hips in time to the music.
"Who knew stress would be a great 5 pound weight loss. Yay for me," Britney gushed in the caption as she posted the home footage to Instagram along with two winking emojis.
Britney was reported to have been struggling in recent weeks after her dad Jamie fell seriously ill and underwent emergency surgery when his colon ruptured.
The singer announced an 'indefinite hiatus' from all work commitments - including her lucrative Las Vegas residency.

If you could do that, I would be forever grateful. Love you."

In January Britney opened up about the family drama in a post on Twitter saying: "I don’t even know where to start with this, because this is so tough for me to say.
"I will not be performing my new show Domination. I’ve been looking forward to this show and seeing all of you this year, so doing this breaks my heart.
"However, it’s important to always put your family first… and that’s the decision I had to make.
"A couple of months ago, my father was hospitalized and almost died.
"We’re all so grateful that he came out of it alive, but he still has a long road ahead of him.
"I had to make the difficult decision to put my full focus and energy on my family at this time. I hope you all can understand.
