Logan Paul got the London crowd going on the hottest day of the year when he rode an open-top bus on Friday afternoon.

The American YouTuber, 27, who has been enjoying fun nights out with Nina Agdal lately, was joined by fellow social media sensation KSI, with whom he collaborated on the new energy drink Prime.

When the bus pulled up in front of an Asda store, an army of fans gathered to catch a glimpse of the duo as they market the product, which was released in the UK on Friday and has been awarded the seal of approval by the likes of Snoop Dogg.
