Identifying herself as T-Swizzle, the country superstar surprised just about everyone when her duet with rapper and producer T-Pain opened the CMT Music Awards in 2009.

The pair appeared in the hilarious promo video for ‘Thug Story’ (a hip hop parody of Swift’s international breakthrough track ‘Love Story’) which saw the singer send up her clean-cut image and show off her surprising rap skills.

Featuring lines such as “I’m so gangster you can find me baking cookies at night / You out clubbing? But I just made caramel delight,’ the 90 second track showed the budding starlet certainly had a sense of humour.

It’s hard to imagine any of today’s pop stars breaking out of their comfort zones and dabbling with rap or hip hop, were it not for Debbie Harry and Blondie’s groundbreaking 1980 single ‘Rapture.’

The New York band, who had found success on both sides of the Atlantic following the punk and new wave explosion of the late seventies, were one of the first rock or pop acts to experiment with the new genre.

Mixing funk, rap and disco, fans were surprised to hear the 'Sunday Girl' singer name-check hip hop pioneers Grandmaster Flash and Fab Five Freddie in the chart-topping smash.

Three decades later fans may still be unsure what Harry’s free flowing lyrics about ‘a man from Mars eating cars’ were all about, but the song is still an undisputed dance floor classic.
