Kate Middleton and Prince William were spotted the other night at famous Julie’s Restaurant in Holland Park — an establishment which once hosted Prince Charles’s stag night before his wedding to Diana Spencer.

The couple sat in booth G1, known to staff as the G-spot because it has luxurious red curtains that can be drawn for extra privacy.

The restaurant is a haunt for showbiz and luvvie types and the table has been occupied by Madonna and Guy Ritchie, Kate Moss and Johnny Depp. Not to be outdone, Sylvester Stallone is said to have removed the bulb out of the light socket while entertaining a glamorous lady friend.

William and Kate, however, were more decorous at the G-spot. An onlooker said, “They enjoyed their meal but their body language was friendly rather than intimate.”

It seems they didn’t even close the curtains, giving fellow diners nothing to gossip about.

Good move.

Prince Harry has been spotted out drinking with Madonna and husband Guy Richie. He is said to have spent more than two hours talking to the so-called Queen of Pop at Mayfair’s Mahiki club.

Big ears listening in say they discussed Madonna and Guy’s adoption of African baby David Banda last October while consuming £100 ($194) champagne Treasure Chest cocktails.

Harry told the couple about the orphans he has befriended in Africa and his charity, Sentebale, which helps thousands of Aids orphans in Lesotho.

One onlooker said: “Harry wasn’t drunk, even though he had a few cocktails from the Mahiki Treasure Chest. The more he talked to Guy about Africa, Aids and the children, the more he was tearful. He seems to be a very sensitive guy.

“He also gushed to Guy about how caring his girlfriend Chelsy is towards the African orphans.”

The conversation moved on to training regimes and how far they ran during exercise. Inevitably the question of injuries came up and caused some mirth in the party.

Harry’s role in the Army probably allows him to advise even a devoted fitness feak like Madonna.
