Diddy loves attention. He loves when everyone looks at him while he is partying. He must have been pissed when he couldn’t get into his own party because there were too many people outside that it was merely impossible to get inside.
So instead if making the grand entrance he loves to make he was forced to get in from the back door.
"They were blocking Diddy's grand entrance," a source told Page Six. "He and his entourage arrived with a three-car fleet of Cadillac SUVs and were forced to turn around. He couldn't even make it close to the front door."
Awww, we’re sure he made it up when he got in.
