Britney Spears's arrest for allegedly driving under the influence was "completely inexcusable", and the incident "can be the first step in long overdue change that needs to occur in Britney's life", her representative has said.
The singer, 44, was arrested in California, Ventura County Sheriff's Office records show.
US website TMZ reported that Spears was arrested for allegedly driving under the influence.
TMZ reported she was arrested at 9:30pm local time on Wednesday.
She was booked into jail at around 3am local time on Thursday.
She was released from jail at around 6am.
The statement issued by Spears's representative said: "This was an unfortunate incident that is completely inexcusable.
"Britney is going to take the right steps and comply with the law, and hopefully this can be the first step in long-overdue change that needs to occur in Britney's life.
"Hopefully, she can get the help and support she needs during this difficult time.
"Her boys are going to be spending time with her. Her loved ones are going to come up with an overdue needed plan to set her up for success for well-being."
Spears, known for hits including Toxic and Oops!... I Did It Again, recently sold the rights to her back catalogue to music publisher Primary Wave.
Spears's lengthy conservatorship, set up in 2008 after her psychiatric evaluation, and which had control of her career decisions and finances, ended in 2021.
In 2007, the Mississippi-born singer avoided a criminal hit-and-run trial by paying for damages after photographers pictured Spears steering her car into another vehicle as she tried to park in a California car park, and walking away after assessing the damage to her own car.
Spears found worldwide fame in the late 1990s, following the release of her hit debut song, Baby One More Time.
During her almost 30-year career, the singer has released a string of pop hits such as Gimme More, Womanizer, Lucky, and I'm A Slave 4 U.
