Britney Spears and Sam Asghari’s relationship might be “Toxic,” according to TMZ. TMZ is producing a Spears doc that will air Monday, and multiple sources alleged to the outlet that the couple’s marriage is in “deep trouble” — and that the 41-year-old singer has reportedly gotten “physical” with her husband. Sources claimed that Spears and Asghari, 29, often get into screaming arguments — and their fights have even gotten so explosive that security has had to intervene.
