London:
Britain's Prince Harry will reportedly have a "traditional" night-out in Las Vegas while undertaking helicopter training in the US.
The 26-year-old will spend two days in the gambling city while undertaking a 12-week training course in California and Arizona later this year.
"It's traditional that guys on his course, which is split between California and Arizona, have a break in Vegas at the halfway point," femalefirst.co.uk quoted a source as saying.
"The course doesn't have much downtime, it's pretty intense. This is a chance for pilots to let their hair down, kick back and enjoy themselves," the source added.
