Celebrities as bridesmaids – from Jessica Simpson to Keira Knightley. They. Are. Gorgeous

Queen Bey acted for bestie Kelly Rowland when she married Tim Witherspoon in early May 2014.

Jessica became a bridesmaid for the second time this week when she slipped into this beautiful royal blue gown for her publicist Lauren Auslander's wedding in Rhode Island.

Keira caused a media storm when she was pictured at her brother's wedding as a bridesmaid. The lovely bride doesn't seem too put out that all the attention's on the Hollywood A-lister standing next to her.

This amazing image sees Lady Gaga looking quite normal - no Kermit dress, no meat slippers (as far as we can tell) - and doesn't she just look lovely?

The Saturdays' singer joined her siblings to celebrate her sister's big day. Her dress and hair is utter perfection, no?

Here's Prince Harry's ex at one of them posh society weddings. She looks nice.

Claudia 'Human Fringe' Winkleman was the maid of honour at best friend Victoria Coran's wedding to David Mitchell.

Back before she was all over our TV screens being all "Get the London look" and pouting, the daughter of Jerry Hall and Mick Jagger was asked to be a bridesmaid at Leah Wood's wedding. She was joined by nine other bridesmaids and flower girls, along with celebrities like Kate Moss and, er, Cilla Black.

Here's Georgia with Rosie Huntington-Whiteley and Alice Dellal at Leah Wood's wedding.

Jessica and husband Cash Warren formed a married-couple partnership with her as the bridesmaid and him as the best man at a close friend's wedding.

At sister Khloe's wedding to Lamar Odom, the whole Kardashian klan were out in full force. Kourtney wore a deep purple...

...Kim was in a dark lilac shade...

...While Kendall wore pastel purple.□

While we probably wouldn't pick brown as one of our wedding themes (we haven't really decided which colours yet, get back to us in a few years, yeah?), it does suit Jessica. Justin Timberlake looks pretty dapper, too.

What's with the black? We do love those cut-out shoulders though.

TV presenter Miquita didn't look too happy to be chief bridesmaid at Lily Allen's wedding to Sam Cooper. Let's hope she cheered up a bit inside.

Arguably the highlight of the 2011 Royal Wedding was Pippa Middleton arriving in that carriage, then getting out. A million men uttered involuntary gasps. A million women immediately got online to buy Fit-Flops in the hopes of attaining such a perfect arse.

And there's the back of that dress in all its glory. Majestic.

Renée Zellweger

Anyone remember 'media personality' Rebecca Loos? Nope? No-one? Let's move on.

Ooh, look at Ms Brook. We like her and the bride's co-ordinating one-shoulder deets, although not sure black is the best choice for a summer wedding...

Another black bridesmaid dress? This time it's former Atomic Kitten Jenny Frost wearing it to perfection.

Yes, we had to double and triple-check this picture too, but it really is Sharon Osbourne acting as maid of honour at Carmen Electra's wedding in 2003.

Ahahhahahahahaha. Hahahhahahaha. Ahahahahhahahahaha. Haaaaaa.

Tee hee, it's nine-year-old Posh and she's actually smiling (front row middle). Adorbs.

Before the Royal Wedding, there was a Royal at a wedding. A young Zara looks very sweet in this bridal gown.

Incredible: vivid metallic lilac gowns, massive golf umbrella to shield the bridal party from the paps. Love it.
