Serena shows off her bag of tricks

She's the undisputed queen of the court and now Serena Williams has shown she can match it with sport's trick shot kings.

With Williams beginning her French Open title defence, footage has emerged of the world No.1 teaming with the tricksters from Dude Perfect to show off her deadly accuracy.

Taking aim at moving targets, it's no surprise the 21-time grand slam winner nails it.

She also has no problem obliterating a water balloon on a string with her powerful serve or knocking a beer can off the top of one of the dude's heads.

However, not to be outdone one of the boys shows off his accuracy with a double court lob into a bucket of water.

Fittingly, Serena ends the session on top, hitting a giant tennis ball into a basketball hoop from the second tier of a tennis court grandstand.

But in the process the seemingly invincible star reveals her one weakness – a fear of heights.

If only grand slams were played on top of high rise buildings her rivals may have a chance.
