2NE1 frontwoman CL made a surprise appearance during Skrillex's DJ set at Miami’s ULTRA Music Festival on Sunday.

CL took the stage wearing an outfit designed by her good friend and fashion designer Jeremy Scott. She then performed a modified version of “MTBD” with A-List guest stars P.Diddy and Justin Bieber helping out onstage.

Viewers livestreaming the performance through the online video platform Twitch TV, gave CL the nickname of “Asia’s Azalea,” in a presumed reference to Australian rapper Iggy Azalea.

CL fans also expressed their exaltation at rapper's performance at the ULTRA Music Festival in online comments.

"Am I the only one who worships CL and Diplo?" wrote 2NE1 fan Sharm XC in a comment posted to the website YouTube on Monday.

But Sharm wasn't the only CL fan thrilled by the rapper's performance.

"She definitely has the it factor," wrote YouTube viewer Zoey T. on Monday. "[CL is] very confident when she performs." 

Started in 1999, the ULTRA Music Festival has reportedly become one of the biggest electronic music festivals in the US.
