Wills was pictured earlier today (9 July) during a visit to the British Sub-Aqua Club and, rather than wander around in his clothes, he seriously got involved.
Making a splash, the Duke of Cambridge donned a snorkel mask and wetsuit before jumping into the main pool at the London centre.
In May, the Prince followed in the footsteps of his father, The Prince of Wales, and grandfather, The Duke of Edinburgh, by becoming President of BSAC - the UK's governing body for scuba diving.
Well, given this, he could hardly shy away from jumping in feet first!
Prince William wasn't accompanied by his wife Kate Middleton or their son Prince George on the official visit. Shame really, as we're sure George would've enjoyed a fun dip in the pool!
