Selena Gomez stormed out of a dinner date with Justin Bieber last night (16.11.12).

The 20-year-old popstar was spotted fleeing a Japanese restaurant in the San Fernando Valley area of Los Angeles after having a huge argument with the Canadian singer within 10 minutes of sitting down together.

A source told gossip website TMZ.com that Selena - who dumped the 'Boyfriend' singer last week after almost two years together because she reportedly didn't trust him - exited the eatery alone and drove straight home but was quickly followed by the 18-year-old heartthrob.

According to photographers, Justin chased Selena back to her house but she refused to open her security gates for him and he left after a few minutes.

The disastrous date came shortly after Justin hinted to his twitter followers he was struggling to deal with their break-up and admitted he was trying to figure his life out.

He wrote: ''Things aren't always easy. There is a lot of pressure. I'm figuring it all out. I'm trying. But I care, I notice, I still hear u. (sic)''

Selena and Justin have had numerous crisis talks about their future together in recent days.

The on-again/off-again couple fuelled speculation of a reconciliation after Justin picked up Selena at the airport before they stayed at her home on Wednesday night (14.11.12) and they were also spotted together at the Four Seasons Hotel in Beverly Hills the following day.

Justin is set to perform at the American Music Awards in LA tomorrow (18.11.12) but Selena will not attend.
