RadarOnline.com has exclusively learned that Bieber’s on-again, off-again girlfriend Selena Gomez was at the 19-year-old’s Calabasas, Calif., home on the night in question when he allegedly hurled eggs at a neighbors’ property, causing more than $20,000 in damage.
Gomez, 21, had attended a party at Bieber’s home with a group of pals, a source close to the situation has confirmed.
She had romantically reunited with the “Baby” hit-maker days earlier, having been photographed riding on Segways in his exclusive neighborhood.
It’s understood Gomez hasn’t spoken to investigators about the incident — she left before cops arrived on the scene that night — and it’s not even known if investigators are even aware that she was at the home.

The leaked texts begin innocently enough:
“Baby come on. I love you,” says Maybe Bieber.
“I don’t buy that bullshit anymore,” Maybe Gomez responds. “I was honest with you and I gave you a second chance. All my friends were right, You’re such an a**hole.”
Dejected Maybe Bieber doesn’t give up: “You’re all I need right now. I know I can make it right with you.”
“U r a drug addict,” she counters. “U need help.”
Then Maybe Bieber goes for the kill:
“Come on. Don’t tell me you don’t miss this,” the text says next to a picture of an erect penis. (RadarOnline notes that Bieber is left-handed, and the person in the photo “grabs his genitals with his left hand.” Case closed.)
