Justin Bieber Keeps It Casual for Birthday Dinner at Mastro's

Justin Bieber treated himself to some steak for his 24th birthday dinner!

The “Sorry” singer was spotted dining at Mastro’s Steakhouse on Thursday night (March 1) in Beverly Hills, Calif.

He kept it casual in a grey sweatshirt, red pants, and white high-top sneakers.

Justin‘s pastor and good friend Carl Lentz was also in attendance, rocking a black leather jacket with colorful patches along with black and red pants and shoes.

Justin reportedly left the dinner around 10:45 p.m.

Earlier that day, Justin grabbed a to-go lunch before meeting up with his mom Pattie Mallette at a go-karting raceway.

“Justin couldn’t wait to hit the race track and let his adrenaline junkie side come out right away,” a source told E! News. “He was very into it and was going faster than anyone. He loved the challenge of racing his friends and he got very competitive about it. He was hooting and hollering having a great time. They all had a fun time and spent several hours at the track before leaving in limos and heading toward Beverly Hills.”
