He’s sweating it out.

Justin Bieber received support from fans after he shared sweaty selfies as he detoxed.

“Detoxxxxxxxxxxx,” he captioned the post on Instagram Sunday, alongside a carousel of close-up selfies, showing off the sweat on his forehead and his red face.

Though the pop star didn’t give more context on how or why he was ridding his body of toxins, several Instagram users offered kind words to Bieber.

“The good one for you, partner! We all want to see you well ❤️🥹,” wrote one supporter.

“please stay healthy and happy,” added another.

“Love you dude keep pushin,” wrote a third person.

“You can do this. Keep going,” added a fourth netizen.

Bieber’s detox comes five months after his rep denied “harmful” allegations of drug use following concerns about his behavior.

The publicist told TMZ at the time that the ongoing rumors about the “Baby” singer’s physical and mental health were “exhausting and pitiful” and showed that “despite the obvious truth, people are committed to keeping negative, salacious, harmful narratives alive.”

The two-time Grammy winner’s spokesperson said Justin, 31, has been in a good place with his wife, Hailey Bieber, after they welcomed their son, Jack Blues, in August 2024.

The “Never Say Never” singer’s rep added that this year has been “very transformative for him as he ended several close friendships and business relationships that no longer served him.”

Despite the publicist’s denial, Justin has been seen smoking joints on multiple occasions, including at Coachella and while on a snowboarding trip with his pals.

Justin has also reportedly been dealing with financial and marital issues.

Last month, a source told “Entertainment Tonight” that the dad of one has been “irritated” by the Rhode founder, 28.

He “feels like Hailey can be superficial about the way their relationship looks in the public eye,” the insider said.

The source also claimed that “Justin’s lack of motivation has been upsetting for [Hailey].”

The tension between the couple has reportedly been affecting how they parent their son, Jack.

A separate source told Us Weekly that Hailey has been “the stable parent and the one keeping the family together” amid her husband’s recent erratic behavior.

“Justin’s been a hard person to deal with recently because of what he’s going through,” the insider added. “It’s been really hard on her.
