The 40-year-old singer, who dated the “Toxic” hitmaker from 1999 to 2002, insisted Britney’s conservatorship – which she has been under since her public meltdown in 2008 – is “just not right”, and he called for everyone to back the pop star.
In a series of tweets, he wrote: “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.
“No woman should ever be restricted from making decisions about her own body.”
“No one should EVER be held against their will… or ever have to ask permission to access everything they’ve worked so hard for. (sic)”
Justin also shared the support of his wife Jessica Biel, and the pair are hoping the courts and Britney’s family “let her live however she wants to live”.
He tweeted: “Jess and I send our love, and our absolute support to Britney during this time. We hope the courts, and her family make this right and let her live however she wants to live.”
