King Bey is dressed in attire befitting European royalty for her Mrs. Carter World Tour promos. But don't get it twisted — true Houston, Texas, royalty co-signed the fact that Beyoncé is down for H-Town. Underground rap icon Bun B himself debuted the remix to her track "Bow Down/I Been On" Friday (March 29) at Houston's KBXX's 97.9 The Box radio station, then posted the song on his SoundCloud page.

The "I Been On" remix features a roll call of Houston notables, with Z-Ro, Scarface, Willie D, Slim Thug and Lil' Keke joining Bun B. He dedicated the remix to the other half of rap group UGK, Pimp C, who died in December 2007, as well as the late DJ Screw.

Credit Screw for the Southern-specific sound that perhaps shocked listeners the most when the song first dropped. Beyoncé's original ending verse stays in place. With her swag in full attack, Bey finishes out the chopped and screwed track. "Shout out to Pimp C/You know we used to sneak and listen to that UGK," she raps, after mentioning that she was in a Willie D music video at 14 years old. The message: Don't question her street cred.

But not everyone is bowing down. Some say Rihanna took a shot at Beyoncé on Friday with an Instagram post, writing, "I only know how to be number 1!! I could use a challenge... How dat feel down there on ya knees, Huh?!"
