Justin Bieber, Cody Simpson Perform Impromptu Acoustic Set In Hollywood: Hailey Baldwin & Madison Beer Watched

Justin Bieber and Cody Simpson surprised patrons at The Nice Guy in West Hollywood on Monday night, when they performed an acoustic set which included their 2014 duet “Home To Mama.”

The Canadian superstar also sang Tracy Chapman’s 1988 classic “Fast Car” and Edwin McCain’s 1998 hit “I’ll be” with Cody providing accompaniment on guitar during their 30-minute show.

Model pal Hailey Baldwin and Bieber’s teen singer protégé Madison Beer were snapped leaving the West Hollywood eatery with the boys.

Social media posts shared by the 18-year-old Topshop model and Beer revealed Madison also sang at one point and was seen larking about with Justin, while Hailey shared a shot of the heartthrob to her Instagram.

Bieber and Beer’s manager, Scooter Braun also got in on the online action and posted an Instagram video of the “Home To Mama” performance.

His caption thrilled, “So I see @justinbieber and @codysimpson jammed last night in la. Good stuff.”

Braun’s clip and another snippet of the same track were later uploaded to YouTube by a fan account.

TMZ also posted video footage to its website.

An audio clip of Bieber singing “Fast Car” was posted by an onlooker.

Madison shared an Instagram video showing her singing at The Nice Guy while the Biebs hummed along in the restaurant.

The 16-year-old’s caption read, “he’s helping her with the backgrounds.”

The “Where Are U Now” singer was also seen in a Snapchat story filmed in a vehicle and posted by Madison, during which he asked the girls if he should wear a pair of socks that he called “toe shoes.”

“The shoes,” Baldwin wrote alongside a snap of Bieber and the aforementioned socks.

At the end of the night when Justin left the venue with Hailey and Madison in tow, one club security guard mistook Baldwin for a fan and loudly asked her, “What are you doing!” while trying to prevent her from getting into a waiting car with the others.

An eyewitness tweeted that the guard then realized his mistake and apologetically told her “Oh no, my bad my bad.” To which the model apparently responded by laughing.

Earlier this year Cody updated Idolator with the news that his and Bieber’s acoustic duets album has been put on a back burner while he focuses on promoting his Free album and Justin completes his new album.
