Justin Bieber sparked hysteria after accidentally flashing his underwear in a restaurant on Wednesday.

The teen heartthrob decided to relax after shooting his special Christmas concert performance for the Today television show. He chose to dine out with his security team at Serendipity 3 in New York City. Justin was hoping to keep a low-profile and arrived in a hooded sweatshirt.

As he sat down at the back of the restaurant he “gave other diners a peek at his underwear with his jeans sliding down at the back”, reports New York Post.

One eagle eyed fan saw him and couldn’t contain her emotions.

“One girl screeched so loud, everyone in the restaurant looked at her,” a source told New York Post. “She shook and fell into her chair.”

Justin did his best to ignore the commotion surrounding his arrival.

The 17 year-old star continued to enjoy eating a chicken pot pie followed by a Forbidden Broadway sundae before settling the bill.
