Britney Spears' Boyfriend Sam Asghari 'Supporting' Star Amid Mental Health Rehab Hell

Britney Spears' boyfriend is "supporting" her after she checked into a mental health facility, RadarOnline.com can exclusively reveal.

The troubled singer and her backup dancer beau Sam Asghari are "still very much together" despite her recent rehab stint.

"He is supportive of her recovery and only wants the best for her but this issue was too big for him to help with.”

RadarOnline.com readers know, Britney checked into a mental health facility after being "distraught" over her dad Jamie's health woes.

Britney is “very unstable right now,” a source exclusively told RadarOnline.com, adding she's “having a really hard time” with her father's recent illness.

“She says that her father saved her life, which he did,” the source explained. “Jamie is not getting any better, so Britney is taking some time out to make sure she is okay.”

The treatment center “wellness” and is located in the Los Angeles area, according to the insider.

The ailing Jamie specifically asked Britney to go to treatment.

“Her father asked her to go, because she means so much to him,” the source said.

Readers know Jamie recently underwent a second surgery following his colon rupture and hospitalization.

In November 2017, the 66-year-old father to Britney, 37, Jamie Lynn, 27, and Bryan Spears, 41, fell “seriously ill” after his colon “spontaneously ruptured,” leaving him hospitalized for several months.

And although a press release issued by the Spears camp said that Jamie is “expected to make a full recovery” after “almost dying,” a source close to the pop princess told RadarOnline.com Jamie’s health is not “well at all” just yet.

“He is having a lot of health complications that are stemming from his initial ruptured colon,” the insider said.

“She is back and forth to Louisiana, but she is not doing great by any means,” the insider said. “You can see it on her face.”

Her father’s medical issues have “really taken a toll on her.”

“She is not sleeping well and is really leaning on Sam right now as a source of support,” the source said. “Thankfully, he is there for her as much as he can be.”

On January 5, a spokesperson for Britney said that she has decided to cancel her entire upcoming “Britney: Domination” residency in Las Vegas to care for her ailing dad.

Reports now say Britney checked herself into the facility about a week ago where she will live for 30 days.
