"After therapy and being too serious it's so nice to be silly!!!!!" the pop star writes.
On Thursday afternoon, the pop star shared a video of herself making a series of funny faces: smiling, tongue out, eyes crossed, etc. She captioned the video -- which was accompanied by symphony-style music -- "After therapy and being too serious it's so nice to be silly!!!!!"
Sam praised his longtime boo in the comments, writing, "Inspiring people to be themselves rather than trying to get others' approval #humble #real."
The video comes after Brit's mental health issues and conservatorship battle sparked the #FreeBritney movement earlier this year.
Last month, after taking a hiatus from Instagram, Britney posted a video addressed to "all of you who are concerned about me," assuring her fans that "all is well." She added, "My family has been going through a lot of stress and anxiety lately, so I just needed time to deal. But don't worry, I'll be back very soon."
Brit's video included a lengthy caption, in which she said that "things that are being said have just gotten out of control," referring to fans' online conspiracy theories about her health.
"Wow!!! There's rumors, death threats to my family and my team and just so many things crazy things being said," the caption continued. "I am trying to take a moment for myself, but everything that's happening is just making it harder for me. Don't believe everything you read and hear... My situation is unique, but I promise I'm doing what's best at this moment."
Britney assured her fans she was staying "strong" and thanked them for their "love and dedication."
"But what I need right now is a little bit of privacy to deal with all the hard things that life is throwing my way," she concluded. "If you could do that, I would be forever grateful. Love you."
Britney's father, Jamie Spears, has had control over much of her life and financial decisions since becoming her court-appointed conservator in February 2008 following her very public breakdown and divorce from Kevin Federline, with whom she shares two sons.
After Jamie's serious health scare in November of last year and Britney's recent 30-day stay at a mental health facility, she's been exploring the possibility of ending the conservatorship. Lynne Spears, who was estranged from Britney until recently, is in favor of supporting her daughter's wishes.
