You can't make these things up!

Justin Bieber rented a private jet to take him from Miami to Burbank yesterday, and it was supposed to leave around 11am EST, but the plane didn't end up taking off until after 8pm!

Apparently Bieber called to say he was running late and showed up at around 3pm, but he said he wasn't ready because he needed to pick up his pet monkey in West Palm Beach. After four hours, the monkey still wasn't anywhere to be found, so get this -- Bieber chartered a helicopter to bypass street traffic and collect his furry friend, according to TMZ.

Biebs documented the drama on Instagram, including a few videos of him in the chopper and on the ground, looking oh so tough...
