Katherine Ryan has revealed she was forced to make a last-minute change to her outfit as she attended Mel B’s wedding over the weekend.

The comedian was among many stars attending the celebration at London’s St Paul’s Cathedral during the weekend. This event marked the third marriage of the Spice Girl with hairdresser Rory McPhee.

Katherine, who is anticipating her fourth child with her husband Bobby Kootstra, talked about her outfit on the latest episode of her podcast, Telling Everybody Everything.

The presenter expressed that she felt ‘incredibly moved’ to be invited to Mel’s wedding as a fan of the Spice Girls. However, she admitted that her outfit was ‘terrible’ after she had to find an alternative to her fascinator.

She said: ‘I looked like s*** at Mel B’s wedding, everybody knows it.’

Katherine revealed she didn’t know how big her baby bump was going to be when she attended Mel’s wedding, and so she had to get a ‘flowy,’ dress.

She added: ‘It almost looks like bed linen. It’s very dreamy.’

Confessing she found it ‘so difficult’ to get ready with her three children around, she added: ‘I don’t have the thinnest arms for it. I’m too pale for it. It was awful – no offence to the designer!’

‘I put my hair down, which was absolutely the wrong way to do it.’ Katherine shared, telling listeners she had previously shaved the back of her neck because of her ‘low’ hairline, meaning she couldn’t wear her hair tied back.

After learning that the wedding’s dress code included hats and fascinators, Katherine said she ordered a ‘beautiful’ headpiece for the day, but at the last minute, panicked it wasn’t the same shade of blue as her dress.

Confessing she had to use a flower to make her own headpiece, she said: ‘I ended up chopping an orchid from my kitchen and sticking that in my head.

“It was giving ugly step-sister. Like I truly s*** the bed on the look.’

Katherine went onto joke that she felt like she ‘ruined the aesthetic’ with her outfit, and said her husband Bobby, who wore a cream suit, ‘didn’t like his outfit either.’

She told listeners: ‘I don’t think we’ve ever looked worse … on like the most important day of someone’s life.’

However, Katherine then gushed that the day itself was a ‘lovely’ one, and she was surprised by some of the names that featured on the guestlist.

She said: ‘Everyone there was like a close personal friend, or family member, or Northern. Y’know someone she really knew. […] It had a real grassroots like true friendship and family vibe. It was a lovely, lovely wedding.’

Mel ensured she pulled out all the stops to ensure her wedding to Rory was a picture perfect day.

After saying her vows, the pair threw a huge ‘party in the sky’ after hiring the Shard in London for the wedding reception.

The Spice Girl was joined by her guests for a meal, drinks and dancing at the Shangri-La venue inside the building which boasts 95 floors and promises panoramic views over the capital.
