Justin Timberlake has joined a number of celebrities voicing their support for Britney Spears and said what is happening to his former girlfriend is "just not right".

The pop superstar asked a judge to end her conservatorship during bombshell testimony in Los Angeles on Wednesday.

Spears, 39, revealed the legal arrangement that controls her life is preventing her from marrying boyfriend Sam Asghari and starting a family.

She told the court it requires her to use a birth control device to prevent her from getting pregnant.

Following the hearing, Timberlake, who had a high-profile relationship with Spears in the late 1990s and early 2000s, said what is happening to his former girlfriend is "just not right".

The actor and singer, 40, said: "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."

Timberlake, who split from Spears in 2002, said he and wife Jessica Biel fully support Spears. In February he apologised to Spears for how he treated her during their break-up.

Writing on Twitter following the hearing, Timberlake added: "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."

He joined a group of high-profile figures sharing support for Spears.

Actress and activist Rose McGowan tweeted: "Britney Spears has every right to be angry. How would you feel if your life was stolen, dissected, mocked? I pray she gets to live your life on her terms. STOP CONTROLLING WOMEN."

During Wednesday's hearing, judge Brenda Penny said a decision on ending the conservatorship cannot be taken until a request is formally lodged with the court.

Samuel Ingham, Spears’s lawyer, said he will discuss the next steps with the star.
