3. Destiny's Child
Beyonce Knowles, Kelly Roland and the other one absolutely smashed the half time show at this year's Superbowl and showed the whole world that there is still plenty of years ahead of possibly the biggest girl band to come out of the USA ever, but don't expect any full reunion tours yet. It goes without saying that Beyonce is one of the most successful musicians on the planet and there is no sign of her coming to the end of her career yet. Kelly has also had a successful solo career, but is still massively in Beyonce's shadow. However, she has had a hugely successful spell as an X-Factor judge on both sides of The Atlantic. This is one band that is likely to reform eventually, though - given that they are all still so young - don't hang around just yet to find out when.
