'She Don't Know A�thing About Tennis!' Beyonce Is Mocked On Twitter

It was a moment that propelled Serena Williams into tennis history books...but it seemed to pass the biggest star in the audience by. 

Beyonce, 34, joined husband Jay-Z and sports fans on Centre Court on Saturday afternoon to watch the women's world number one - and her close friend - Serena clinch her 22nd career title.

But it seems the global pop icon isn't exactly au fait with how you win a tennis match. When Serena hit the winning shot to defeat opponent Angelique Kerber 7-5, 6-3, the crowd leapt to its feet - but it took Queen Bey a little longer to register what had actually just happened.
