Chris Brown and rapper Bow Wow were unwelcome Wednesday night. First, the duo crashed the listening party to which they weren’t invited for Drake’s new album at MSR studios hosted by the Cash Money crew.

Next, Brown and Bow Wow popped up at Meatpacking club SL — but were turned away by security.

“They showed up with a huge entourage all trying to get in, but they were totally denied at the door,” a spy tells Page Six.

The rejected posse finally found refuge at Greenhouse, where they partied with Brandy and her brother Ray J into the wee hours.
