London: Prince Harry is terrified that Ryan Lochte will spill the beans on his wild Las Vegas antics when he appears on a tell-all TV show.
The double gold medallist, who took part in an impromptu 3am pool race with Harry in Sin City, will talk about their exploits in a new reality series, the Daily Star reported.
An insider at the E! network, which begins broadcasting 'What Would Ryan Lochte Do?' next month in America and in the UK in May, said: "He isn't pulling any punches in his descriptions of the high jinks that happened in Vegas."
Lochte is almost certain to heap further embarrassment on the 28-year-old prince for his naked romp in a Vegas hotel.
Now it is feared Lochte will reveal all about what went on at a steamy party at the MGM Grand, where he and Harry hired luxury poolside cabins to entertain friends privately.
