Rita Ora left London, hiding beneath a cap and dark shades while walking with her head down as she prepared to board a flight to the U.S.

Rita's a coach on the U.K.'s version of "The Voice", and she's in hot water after she appeared on the BBC's "One Show" Monday wearing......well, this:

Yeah, I know.

The BBC received over 400 complaints and was forced to issue an apology which read: "If we had been consulted we would have requested she wore something more suitable for 7pm."

She's already getting a bad reputation for being "naughtier" than her predecessors on the BBC's "Voice" (Kylie Minogue and Jessie J), and she's admitted that she's already bracing herself for a Twitter backlash as she replaces the previously popular songstresses in the chair.

If Rita needs a place to crash when she hides out in America I've got a fold-out couch she can use..............
