We all know Kanye West is pretty much renowned for cracking endless jokes and refusing to stop smiling, right? Oh wait, maybe not. Still, despite his usual straight-faceddemeanor, Kim Kardashian's hubby was feeling a little mischevious on Monday morning.

The musician decided to pull a prank on the paparazzi as he appeared to wee in the street while his Keeping Up With The Kardashian's star bae covered her face and giggled.

Take a look at MTV News to see Kylie Jenner's first video of baby Stormi Webster...

While you would be forgiven for thinking he was taking an actual whiz, sources have confirmed the rapper was just feeling a little playful and putting on a show for the cameras.

Who knew Kanye was such a top joker?

The 40-year-old and Kim were outside a warehouse in downtown LA when he decided to strike the suspicious pose, tbh he probably thought everyone would be too busy looking at Kim's bright pink hair to notice.

The reality star complimented her new do with a striking pair of snakeskin boots, a pair of figure-hugging trackies and a cosy fleece.

One thing is for sure, those two certainly know how to get noticed.

Now take a look at the video to see Sophie Kasaei, Olivia Buckland and LateyshaGrace talking about all things sex (with no topic off limits) in that'swhat she said...
