American Idol judge, singer and actress Jennifer Lopez has been named the most powerful celebrity in the world by Forbes magazine.
Lopez took the number one spot in the Celebrity 100 list, toppling Lady Gaga who has fallen into fifth place.
J.Lo is not just a performer - she is also a successful businesswoman with her own perfume and fashion line. She has also endorsed products for cosmetics giant L'Oreal.
By comparison, Lady Gaga, who first hit the international stage with her single Poker Face, is a relative newcomer.
Media mogul and TV presenter Oprah Winfrey remained in second place
