Prince Harry could head back to Sin City Las Vegas for a wild boys-only party to celebrate William and Kate's baby arrival.
Harry, nicknamed Elvis by US troops, was "delighted" by the news of his sister-in-law's pregnancy.
However, pals said that the Duchess could be embarrassed if Harry overdoes the baby celebrations.
The 28-year-old Royal, who made headlines when he was snapped naked in a game of strip billiards at his hotel, is said to be itching to repeat his August trip when he completes his current tour of duty in Afghanistan, the Daily Star reported.
"A lot of the boys are trying to get Harry to go on another trip to Vegas when their service is done," a US military source added. (ANI)
