Serena Williams + Kate Middleton + Snapchat = too much awesome to handle

Updated: 

Serena Williams only needed 48 minutes to book her place in the Wimbledon final - so she needed to find another way to amuse herself.

And after beating Elena Vesnina in straight sets in her semi-final, she found a pretty decent way to fill her time: hanging out with the Duchess of Cambridge.

Serena sent the video of herself, Kate and the Countess of Wessex out on Snapchat, and the video quickly did the rounds on social media.

If that isn't the very definition of #squadgoals then we don't know what is.

Kate was in the Centre Court royal box to watch both Williams sisters in action - Venus lost to Angelique Kerber of Germany in the other semi-final.

Angelique will now face Serena in the final on Saturday.
