Despite the sheer volume of media coverage it turns out Fearne's still just as excited as we are: "I'm thrilled about the whole thing. Millions of my friends are having fancy dress parties and royal wedding parties - I love the community sense of people doing street parties and stuff!
"Finding out what Kate's going to wear is going to be one of the biggest moments in fashion for years. I think everyone's just waiting. It's like when Princess Diana chose that dress - all eyes were on the dress and how she walked in it and what it looked like down the aisle. It was a real fashion moment and it really depicts the eighties. Now we're in 2011 and Kate's dress needs to represent that. I'm really excited – I can't wait to see what she wears."
So what might that 2011-tastic frock be?
"I think something really sleek. She's so gorgeous and has the most amazing body so something really sleek and simple. Something cut really well that hangs really beautifully. I think the days of the puffball dress have gone - although she'd still look amazing in that. She could rock anything but I think something really understated and simple would look great on her."
Fearne also has a bit of a personal connection to one half of the royal couple as she interviewed Prince William and Prince Harry in 2007: "[It] was a real moment for me so I wore this chiffon orange dress with no jewelry and kept it simple to be respectful! That dress has special memories."
Is she tempted to bring it out of retirement for 29 April? "No! That dress will never be worn again. It's had its time and that's that! One wear and it will be preserved forever."
And on the rumoured four pairs of shoes Kate will be wearing? "You're going to be a princess. Do what you want!"
Our full interview with Fearne will be appearing on the site soon. Her summer collection for Very.co.uk is available now.
