Prince Harry Prince Harry There's been some right royal antics over the weekend.

But fret not ladies, the stag do was for one of the Princes' cousins.

If the Queen is reading this, we'd advice ma'am to read no further... to save her royal blushes.

So, Prince William and Prince Harry gave Princess Anne’s son Peter Phillips a stag weekend to remember.

The jaunt began last Friday morning as the stag party boarded a high-speed ferry from Southampton to Cowes on the Isle of Wight.

Peter was forced to swap his clothes for a skin-tight white leotard. Delicious.

Once on the island the mayhem really began - that's when William and Harry arrived to join the fun.Prince William

According to The Sun, the stags were hitting the local pub within hours.

At the boozer, the group spent hours playing pool and partied to a band.

Astonished local Sophie Bleak told the paper: "I was just sitting watching the band when Prince Harry came over holding a funnel and a pint of beer and said I had to have a drink.

"He put the funnel in my mouth and began pouring lager down it - but after two gulps I had to give up. He laughed, gave me a big hug and told me to have a good night.

"It was incredible seeing those two guys in here out on the beer with just the ordinary locals.

“Harry and William were as good as gold."

On Saturday morning, the 23-strong group went down to the marina in Cowes for a day of sailing.

Harry said as the bash drew to a close: “It’s been an awesome stag do - it will just take us a while to recover.”

Peter is due to wed his lady, Autumn Kelly, at St George’s Chapel at Windsor Castle on 17th May.

Asked how he was coping with the weekend, he joked: “I’m still alive.”
