Sarah Ferguson's hat threatened to upstage the bride as she and her ex-husband accompanied each other to the royal wedding of Lady Gabriella Windsor.
Lady Gabriella - known as Ella to her friends - wed her financier husband Thomas Kingston at St George's Chapel in Windsor Castle today, surrounded by their family and famous friends.
And Fergie was right in the centre of activities as she turned up alongside ex Prince Andrew and her daughter Princess Beatrice wearing showstopping pink.

The Duchess of York opted for a curve-skimming knee-high dress with a scoop neckline and an exaggerated ruffle over the left shoulder.
The soft pink number featured three-quarter-length sleeves and a flattering nipped in waist.
Sarah, 59, paired it with pointed burgundy court shoes and a matching clutch bag - as well as that hat.
The shapely curves of the pastel pink headpiece echoed the lines of her dress, and added a touch of drama with the inclusion of a sprig of colourful patterned feathers.

The Duchess accessorised with a silver brooch in the form of a bird in flight, as well as gold bracelets at her wrists.
Sarah and Andrew divorced back in 1996, but have become firm friends over the years.
They even live together at the Royal Lodge in Windsor - and have recently been the subject of rumours that they're 'friends with benefits'.
However, one person said to be less than impressed by their are-they-aren't-they romance is Andrew's big brother Prince Charles, who allegedly still holds a grudge against Fergie for backing Princess Diana during their split.

But Fergie's long-time opponent Prince Philip - who fell out with her after those infamous toe-sucking pictures ended her marriage to Andrew in 1992 - has done a shock u-turn.
In April, a spokesperson for Sarah and Andrew denied the reunion chatter, insisting: "The Duke and Duchess of York continue to be good friends and nothing has changed in their relationship."
However, a senior Palace source told the Mirror: "While Duke and Duchess are not officially back together, it is fair to say their relationship is incredibly strong.

"The two of them are not involved in relationships with anyone else, which of course likely to fuel rumours of an unlikely reunion.
"They very much enjoy each other's company and their public displays of affection for one another are becoming more frequent.
"With one daughter happily married and the other in a serious relationship that could well end in marriage, maybe the focus will shift back to them.
"But for now they are enjoying spending time together and as a family."
