Prince Harry's ex Chelsy Davy does a Pippa Middleton and upstages the bride at the poshest wedding ever

If Chelsy Davy was nervous about running into her ex-Prince Harry at a mutual friend's wedding she sure didn't show it.

The Zimbabwean socialite stole the show as chief bridesmaid on Saturday at the poshest wedding since KMidd and Prince William's do back in 2011.

The wedding of Lady Melissa Percy and Thomas van Straubenzee (no really, those are their names) was attended by everyone who is anyone in British high society, including most of the younger members of the royal family.

Both Princes William and Harry acted as ushers in the ceremony while Princesses Beatrice and Eugenie were also in attendance.

This wedding was so posh the reception was held at Hogwarts!

Actually it was held at Alnwick Castle, which was used in place of the magical school when filming all eight Harry Potter films, but that's pretty close.

Chelsy pulled a total Pippa Middleton and upstaged the poor bride in a caramel coloured sheath bridesmaid dress that gave Harry a taste of what he is missing.

The trainee solicitor dated Prince Harry on and off for six years before finally splitting in 2010 and in a further twist, Harry's current girlfriend Cressida Bonas was also at the nuptials.

But Chelsy kept her head held high and seemed as if she didn't even notice her former beau (who happens to be third in line to the crown) was there.

With even Pippa Middelton making an appearance at the wedding in Northumberland, the only person missing was the Duchess of Cambridge who is just weeks away from giving birth.
