Britney Spears and husband Sam Asghari secured a restraining order against her ex who was arrested on an outstanding warrant after trying to crash her wedding while armed with a knife, police say

• Britney Spears and new husband Sam Asghari now have a restraining order against Jason Alexander.
• Alexander, who was briefly married to Spears in 2004, attempted to crash her wedding on Thursday.

Britney Spears and her husband have secured a restraining order against Jason Allen Alexander following his arrest Thursday, the Ventura County Sheriff's Office confirmed to Insider and was first reported by Page Six.

Authorities added that Alexander "had a knife in his possession" but it was never "brandished."

The order comes after Alexander — who was married to Spears for 55 hours in 2004 — live-streamed himself attempting to crash Spears' and Sam Asghari's wedding on Thursday.

The order will offer five court days — seven calendar days — of protection. It bars Alexander from being within 100 yards of the couple or their property in Thousand Oaks, California, per Page Six.

Alexander was arrested Thursday for an out-of-county warrant and faces charges of battery, vandalism, and trespassing.

"This was an outrageous security breach, which I am livid about, but fortunately Britney is safe and she was a stunning and happy bride," Spears' attorney Mathew Rosengart told Page Six. "I'm working closely with law enforcement to ensure Mr. Alexander is aggressively prosecuted to the fullest extent of the law."

Rosengart did not immediately respond to Insider's request for comment.

Spears and Alexander were childhood friends and surprised the world when they got married in Las Vegas in 2004. But the union was brief — the marriage was famously annulled just 55 hours later.

Now Spears is married to Sam Asghari, an actor and personal trainer who met the pop star while working on the set of one of her music videos. Spears and Asghari dated for nearly six years and wed on Thursday night at the singer's mansion in Thousand Oaks, California (a city nearby Los Angeles).

While a wedding tent was being set up in the backyard of Spears' home, Alexander live-streamed himself entering the property a few hours before the ceremony was set to take place. The video was reportedly broadcast live from Alexander's Instagram account.

A Twitter account devoted to Spears shared a screen record of video that shows Alexander giving a tour of the inside of a wedding tent, where he says "here's the inside scoop at the bullshit wedding." He also says that he's "crashing" the event.

Sheriff's deputies arrested Alexander at the venue. His arraignment is set for Monday at 1:30 p.m PT.
