POP diva Lady Gaga may have taken the No.1 spot in the Forbes magazine Top Ten of the 100 most powerful celebrities but it’s not a genuine indication of worth.

She’s pushed TV star Oprah Winfrey, pictured, into second place with the likes of actor Justin Bieber, rock band U2, Elton John and Tiger Woods in her wake.

Lady G may be a pop and style icon and understand the value of shock tactics, but when it comes to power she has plenty to learn from Oprah.

The American talk show host, billionaire and philanthropist, has been hugely influential to life in the US and in countries around the world. And she did it without ever wearing an outfit made of meat.
