Strolling through Beverly Hills on Thursday, Ronnie Magro and Jen Harley assured a TMZ cameraman that all was well in their relationship, and they'd finally put the drama behind them.
Within 12 hours, however, Ronnie was in police custody following a violent altercation with Harley.
According to TMZ, cops arrived on the scene in response to several 911 calls indicating that Jen was "in distress."
Fearing that the couple's 1-year-old daughter, Ariana, might be in danger, police broke down the door with a battering ram.
And that's when the situation really got out of hand.
Take a look:
How Quickly Things Change
This was Ron and Jen in Beverly Hills on Thursday, assuring TMZ that all was well and that they had never been happier.
Ronnie told the pap that "everything's good" in his relationship with Harley, adding that the couple's strategy for coping with the negative press around their relationship is to "just ignore everybody."
At 2:30 the following morning, however, amid reports of a violent altercation within the residence, police were called to the Air BnB Jen and Ronnie were renting
Insiders say Magro stands accused of slapping and punching Harley during a heated argument.
A Chaotic Scene
Fearing that the couple's daughter might be in danger, police forcibly entered the residence.
It's unknown who called 911, but they described an appalling scene in which Ronnie chased Jen with a knife while she held Ariana in order to protect the baby.
When police arrived, Ron had dropped the knife, but was now hiding in a closet with Ariana.
Cops forced their way into the closet and were able to usher Ariana to safety. But Ronnie still refused to come peacefully.
That's when police decided to rase Magro in order to subdue him.
Fox 11 LA reports that a semi-conscious Magro was led from the scene on a gurney and loaded into an ambulance.
Police tell TMZ that Magro will be arraigned as soon as doctors give the go-ahead.
Off the Wagon
Jen told police that Ronnie had been doing cocaine, which may help to explain his erratic behavior.
Obviously, that's no excuse for the appalling way in which he behaved, but it serves to explain how Ronnie wound up in such a troubling state.

At one point, he had six months of sobriety under his belt. Sadly, it didn't last.
Not Even Hiding It

No More Shore For Jen
On Thursday night's episode of Jersey Shore Jen re-entered Magro's life following an invitation from his roommate, Jenni Farley.
The Breakup Speech
Ronnie poured his heart out to his roommates, opening up on all the low points, the fights, and the destructive behavior that have defined his tumultuous time with Harley.
