Chanel West Coast Throws Epic Tantrum After Coachella Denial (VIDEO)

Chanel West Coast pulled a Justin Bieber at Coachella -- minus the chokehold -- and flipped out on camera when security guards turned her away from a VIP area.

According to our sources, the rapper and "Ridiculousness" star was with her boyfriend and another friend Saturday when they tried to get into the "artist's entrance" area, which of course requires a special wristband.

Problem was ... she had the wristband, her boyfriend had the wristband, but the friend did not. Security wouldn't give in, despite Chanel dropping Drake's name and Young Money (that's her label).

She stormed off, but Chanel tells us she and her friends did make it through the proper entrance a short time later, and partied the night away.
