Essex stars Lauren Pope and Vas J Morgan took on Chelsea favourites Rosie Fortescue and Proudlock in a zorb-off at London's Westfield shopping centre on Monday (27 July).
FYI: A zorb-off is the totally technical name for competing in the shopping mall's new water zorbing experience!
These guys are four of the most fashionable and stylish reality stars on either side of the planet but it was all about the sensible shoes and sports clothes yesterday as they took the challenge very seriously!
So, who won? Well, judging from these pictures, we honestly can't tell! It seems like all four had a bit of trouble staying upright in the water!
If you fancy following in their footsteps, head over to Westfield's Summer Beach Club, where you too can climb into a giant inflatable ball and roll it around in a pool of water.
Sadly, we can't guarantee Lauren, Vas and co. will be there to do it with you!
Ten reasons we want to be on TOWIE!
