Britney Spears' testimony prompts reactions from Justin Timberlake and more stars: 'Stay strong'

Britney Spears did not hold back while addressing the court about her conservatorship on Wednesday.

The 39-year-old pop star called her legal guardianship – overseen largely by her father Jamie Spears – "abusive" and said it left her "traumatized" after 13 years of not having access to her own money and making her own life decisions. She formally called for the court to end the ordeal.

She alleged that she has been barred from removing contraception from her body that prevents her from conceiving a child and that her boyfriend, Sam Asghari, has not been allowed to drive her in his car.

As Spears' comments and allegations poured in, several celebrities spoke out in support of the star.

Among those to offer support was Justin Timberlake, who previously dated the star and recently offered up a public apology for his handling of their breakup, which received criticism for painting the "Toxic" singer in an unflattering light.

"After what we saw today, we should all be supporting Britney at this time. Regardless of our past, good and bad, and no matter how long ago it was… what’s happening to her is just not right," he began. "No woman should ever be restricted from making decisions about her own body."

The star continued: "No one should EVER be held against their will… or ever have to ask permission to access everything they’ve worked so hard for. 

"Jess and I send our love, and our absolute support to Britney during this time," he added of him and his wife Jessica Biel. "We hope the courts, and her family make this right and let her live however she wants to live."

"We love you Britney!!!" said pop star Mariah Carey on Twitter. "Stay strong."
