The singer accidentally said "f**king hell" while being interviewed on Huey Morgan's BBC 6 Music radio show this morning, reports the Metro.
During her appearance on the show, Morgan asked the star whether she was "bugged" by the hype currently surrounding her.
Del Rey responded: "Not really, I mean, only because it's been so long that I've been singing now - it does feel different 'cos the circumstances are different but the music is the same still, thank God."
Del Rey also admitted that she was asked to "try and write something upbeat" after she put 'Video Games' out last year. Responding to Morgan's joke that 'Born To Die ' was that track, she laughed: "Yeah, another song to kill yourself to!"
The BBC has since removed Del Rey's "f**king hell" from the online streamed version of the session, which is available on the station's homepage.
Lana Del Rey's debut album Born To Die will be released on January 30.
