Justin Bieber closes his eyes for a quick second as he arrives at the Johannesburg airport in South Africa on Wednesday afternoon (September 22).
The 16-year-old musician tweeted his exhaustion to the world, saying, “Wow. I am so tired.. Good thing this flight is going on a 30 hours.. That’s right I’m going to be the youngest person to go to the moon.”
Justin is taking a mini-vacation before his next concert in Hawaii.
