The current list of famous celebrities will remain incomplete without the inclusion of Stefani Joanne Angelina Germanotta, popularly known as Lady Gaga- an acclaimed American pop singer. Her debut album- The Fame- was released in 2008. The album became an instant hit, with the singles- "Poker Face" and "Just Dance"- achieved international fame and made her immensely popular. The album was a huge commercial success and reached the top slot on the record charts of as many as six countries. It even topped the Billboard Dance/Electronic Albums chart. Her follow-up album- "The Fame Monster" too achieved worldwide success and produced some chart-topping singles, such as "Telephone" and "Bad Romance."
Her popularity can be gauged from the fact that the TIME Magazine included her in its annual Time 100 list of the most influential people worldwide. Thanks to her increasing popularity and immense fan following, Lady Gaga was placed at number seven by the Forbes Magazine in its list of World's 100 Most Powerful Women. She also won two Grammy Awards for "The Fame" and "Poker Face."
