The 68-year-old -- who the singer says should "be in jail” -- was spotted for the first time since the Grammy-winner's explosive testimony last week.
Jamie Spears looked as if nothing was wrong, chatting with a fellow patron as he signed papers behind a Monster Energy booth.
Britney's estranged dad lives in an RV that he parks outside of a warehouse in Louisiana near the star's hometown, despite collecting $16,000 per month and an extra $2,000 monthly for office space from his oldest daughter as her conservator.
Wearing glasses and his Monster Energy hat, Jamie Spears looked cool as a cucumber while talking to a buddy from inside what looked like a storage unit.
Jamie's RV was also photographed and revealed to be a Dutchmen 'Denali' fifth wheel, which retails for around $35,000.
Interestingly enough, while he battles one daughter in court, he's seemingly showing his support to another.
Monster Energy has longtime sponsored 30-year-old Zoey 101 star Jamie Lynn Spears, who has copped major heat for not speaking out in support of her older sister.
On Wednesday, Britney spoke to the judge about her conservatorship for the first time in 13 years, and begged for their talk to be public.
The singer didn't hold back, comparing her conservatorship to "sex trafficking" and telling the judge that her dad should be locked up.
Everything Britney said was disturbing -- from her team allegedly putting her on lithium to denying her private therapy from home -- but the most troubling might be the fact she has no control over her body.
Speaking to the judge, Britney Spears revealed she wants to get married and have a baby, but Jamie is preventing her from doing so.
“I want to get married and have a baby,” she said during her emotional testimony. “I want [the IUD] taken out so I can start trying to have another baby. But this so-called team won’t let me go to the doctor to take it out because they don’t want me to have any more children.”
Britney also said she wants to sue her dad following the alleged mistreatment he allowed her to endure for over a decade.
She wants out of the conservatorship and to end Jamie's long reign over her life.
As for Jamie, he spoke out through his lawyer claiming, he's "sorry to see his daughter suffering and in so much pain."
