Inside the royal wedding after-party

WHEN George Clooney gets stopped at the door by security, you know this was some party with serious star power.

The Hollywood celebrity and his lawyer wife Amal were forced to prove themselves to Windsor Estate guards, as the couple arrived in their silver Audi S5 ahead of the Frogmore House reception for the newlywed Prince Harry and his bride Meghan.

It was a rare blip in the seamless execution of the royal wedding of the decade, which may - for all we know - be still going in a private members' club or stately home in London.

While 200 guests were welcomed back to the evening reception, after a 600-strong congregation attended St George's Chapel for the ceremony itself, an after-party was said to be raging on at Chiltern Firehouse, a late-night hot spot in Marlyebone, owned by the groom's pal, Andre Balazs (Katherine Keating's ex).

Those still standing after the joyous, but long wedding day, could at least ease out of their stiletto heels after being gifted with monogrammed slippers at the reception, which ended in an explosion of fireworks around 2am.

Dancing the night away in a $600,000 glass marquee, purpose-built for the evening gala (hosted by Prince Charles) a DJ who played the reception of Pippa Middleton's wedding last year had the celebrity guests fired up.

Sir Elton John got guests in the party spirit at the earlier luncheon, when Prince Harry ended his touching tribute to "wife" Meghan by pointing at a piano and asking the A-list crowd "does anybody know how to play?"

Stepping up, as he did on the sad occasion of Diana's funeral, the pop icon then played a mini-concert set including Tiny Dancer, Circle Of Life, I'm Still Standing and Your Song.

Sipping Pol Roger vintage champagne, guests were served canapés and food bowls, as opposed to a sit down luncheon, using local and organic sourced ingredients, including 10-hour roasted pork belly and Scottish langoustines.

Many guests, including Meghan's power posse of fashionable friends, paraded into the post-

wedding event - emceed by actor James Corden - in gowns worthy of the Oscars red carpet.

Priyanka Chopra, a former star on Quantico and Baywatch, sparkled in a sequined pewter-coloured gown by Dior; while her Canadian bestie, Jessica Mulroney went for gold in a body-hugging dress, with plunging neckline and sexy cowl back.

Mulroney drew some criticism for "showing off" by having her stylist Rachel Renna post video and photos of her parading around in the gown.

Meanwhile, Chopra posted a touching tribute to Meghan on her Instagram, celebrating the occasion.

"Every once in a while there is a moment when time stands still … that happened today. You, my friend," she wrote to the bride, "were the epitome of grace, love and beauty. Every choice made at this wedding by you both will go down in history, not just because it was your wedding but because this incredible wedding stood for change and hope. Both things that the world needs desperately.

Thank you for being the perfect picture of all things good. Seeing your union and love blessed in front of my eyes made me so happy … and tear up! I wish you both love, happiness and togetherness always."

Watching the Brits watch an American Preacher do his thing in Windsor is giving me life right now. It's like watching Metallica do a concert in the Old Globe. #RoyalWedding
