Eminem surpassed Gaga's feat in February (11) and, by March (11), he had stolen the crown from the King of Pop too - with more than 30 million votes.

Now Gaga has taken another knock to her ego - Rihanna has replaced her as the most-liked female star on the site, racking up more than 40.5 million 'likes' - a far cry from the 5,000 she had last summer (10).

However, Gaga shouldn't be too upset - she still rules over Twitter.com with over 11.6 million followers.
