Bieber and Gomez had a short surprising dinner amid seperation rumor

In that famous disastrous dinner

Justin Bieber and Selena Gomez brought themselves in a surprise dinner Friday in a Japanese restaurant. The tween power couple got in an epic argument during dinner and they didn't even make it to the appetizer. Bieber and Gomez had barely spent 10 minutes with their meal in the San Fernando Valley Japanese restaurant "Yamato" before they got into an argument.

The 20-year-old starlet stormed out of the scene, with the 18-year-old Canadian heartthrob following her with his head bowed, TMZ reports. "Something must have happened inside the restaurant, because 10 minutes after he arrived, they both stormed out looking stone-faced," a source told E! Online.

"They were very serious and did not look happy at all. She got in her car, and Justin got into his." Gomez then drove home, while Bieber training her car behind, only to be rejected at the gate of her LA home. "Selena drove off and Justin just sat there for a few minutes. I think he was waiting for her to calm down. He then drove to her house. When he got there, he started buzzing her gate. But she was obviously not letting him in. He continued trying. Then, after a while he got out of his car, he was obviously frustrated and went up to the gate and started yelling 'Selena' over it. But...she was not coming out," the insider added. "It was at this point [Justin] started to yell at the paps," the source told the site.

"He was obviously annoyed that they were there and witnessing everything. He was mad. Selena then came out, because there was such a commotion, he got in his car and left." That wasn’t the end of the story, for the source continued, "something must have happened overnight, though, because his car was there this morning."

According to a photog on scene ... Selena drove home with Justin trailing a few minutes behind. When Justin got to her place ... she denied him entrance at the gate and Bieber drove off. The troubled teen idol duo's romance only seems to get more dramatic. And Bieber seems to be taking it all in to learn some life lessons. "Things aren't always easy," Bieber tweeted later that night.
