On Friday, two days after Bieber, 18, and Gomez, 20, reunited in Los Angeles, they had a showdown at Yamato, a Japanese restaurant in the San Fernando Valley, Calif., according to an observer.
Just five minutes after entering the restaurant, the pair who split earlier this month after two years of dating, emerged again – with Selena looking visibly "mad," says the source.
After leaving in separate cars, Bieber followed Gomez home, only to be turned away at the door. TMZ.com posted photos of an angry looking Bieber outside a gated driveway.
Later that evening, Bieber Tweeted a cryptic message. "Things arent always easy," he wrote. "there is alot of pressure. im figuring it all out. im trying. but i care, i notice, i still hear u. #Beliebers"
