Teen actress Emma Watson has been crowned the biggest-grossing female star of the last decade by The Guinness Book of World Records. The 19-year-old star, best-known for her co-starring role as Hermione Granger in the six Harry Potter films released so far, has clinched the win with $5.4 billion in global box office receipts.

And her total will continue to tally when she appears in Harry Potter and the Deathly Hallows 1 and 2, in 2010 and 2011 respectively.  Following Watson as the second top-earning actress was her Harry Potter co-star, British actress Maggie Smith, whose films Gosford Park and The Divine Secrets of the Ya-Ya Sisterhood grossed $88 million and $74 million at the global box office respectively.
