Newlyweds Britney Spears & Sam Asghari Get Restraining Order Against Her Ex Jason Alexander After He Crashes Nuptials

Better safe than sorry! Less than 24 hours after Britney Spears' ex Jason Alexander tried to crash her and Sam Asghari's wedding on Thursday, June 9, the spouses have been granted a restraining order, Page Six reported.

The singer's infamous former flame, who allegedly had a knife on him, must stay at least 100 yards away from her home in Thousand Oaks, Calif., which is where her nuptials were held. He's currently behind bars, and the publication said Alexander's arraignment is scheduled for Monday, June 13.

"Fortunately, Alexander is incarcerated and under an Emergency Protective Order," the mom-of-two's attorney Matthew Rosengart shared with the outlet. "I want to thank Sergeant Cyrus Zadeh, Detective Ken Michaelson, and the Ventura County Sheriff’s Office for their prompt and good work and look forward to working with law enforcement to ensure Alexander is aggressively prosecuted and hopefully convicted, as he should be."

"This was an outrageous security breach, which I am livid about," the lawyer noted. "But fortunately Britney is safe and she was a stunning and happy bride."
