Dressed in dapper suits the all-male group can be seen performing an awesome a cappella (no use of musical instruments) version of Shakira's hit numbers -- 'Hips don't lie', 'Waka Waka' and 'Whenever Wherever' -- in this viral video that has crossed three million clicks in just over a week. The crooning British men impressed the Colombian diva so much she took to Twitter to shower praises on them, other than tweeting their video and as expected nothing could stop it from going viral. "Hey @ootboxford, we LOVE your a capella Shak medley! ¡Nos encanta este medley que han hecho @ootboxford!@shakira," Shakira tweeted.
