Britney Spears is being used as a secret weapon‚Ä¶ to scare off Somali pirates.
Her hits are blasted out to deter kidnap attacks, merchant navy officer Rachel Owens revealed.
Spears‚Äôs chart-toppers Oops! I Did It Again and Baby One More Time have proved to be the most effective at keeping the bandits at bay.
Second Officer Owens, who works on supertankers off the east coast of Africa, said: ‚ÄòHer songs were chosen by the security team because they thought the pirates would hate them most.
‚ÄòThese guys can‚Äôt stand Western culture or music, making Britney‚Äôs hits perfect.‚Äô
Ships in the region are in constant danger from gun-toting pirates boarding and kidnapping crews for multi-million-pound ransoms.
In 2011, there were 176 attacks on ships by gangs of bandits off the Horn of Africa. They are such a threat the Royal Navy has 1,500 sailors on 14 warships operating round-the-clock patrols in the area.
Ms Owens, who regularly guides huge tankers through the waters, said the ship‚Äôs speakers can be aimed solely at the pirates so as not to disturb the crew.
‚ÄòIt‚Äôs so effective the ship‚Äôs security rarely needs to resort to firing guns,‚Äô said the 34-year-old, from Gartmore, near Aberfoyle, Stirling.
‚ÄòAs soon as the pirates get a blast of Britney, they move on as quickly as they can.‚Äô
Steven Jones, of the Security Association for the Maritime Industry, said: ‚ÄòPirates will go to any lengths to avoid or try to overcome the music.‚Äô
He added: I‚Äôd imagine using Justin Bieber would be against the Geneva Convention.‚Äô
