The 28-year-old star says wellies are still her "ultimate" festival accessory, but she always packs a few key things to help her feel glamorous even if it's raining.
Asked about her top summer festival essentials, the Littlewoods designer, who will be at Virgin Media V Festival Louder Lounge and Virgin Media Our House this weekend, said: "Knowing how interchangeable the UK weather can be, I always make sure I come ready for all conditions. You never know what might happen once you're out having fun in a field!"
Discussing her obsession with wellies, she described them as her "ultimate must-have festival outfit item."
She added: "I never let a traditional English downpour dampen my festival spirit! Pack a good raincoat and embrace the weather, whatever it decides to do."
She also prepares to make the most of any sunshine, but never brings her favourite designer sunglasses to the campsite.
She said: "I'd be lost without my summer sunnies, although I never take my fave pair to a festival because they don't always make it home."
But Coleen always brings mascara and make-up wipes.
She explained: "You can't beat the feeling of removing all that dirty festival grime at the end of hard day's partying."
Meanwhile, the brunette beauty - who is married to Wayne Rooney - is a huge fan of 'Sing' hitmaker Ed Sheeran and is hoping to bump into him this weekend.
She said: "I'm really excited to be heading to V Festival again this year for some fun, especially at the Virgin Media Louder Lounge. It's always so chilled and makes the day extra special. I'm most looking forward to seeing Ed Sheeran perform, I'm hoping I bump into him at some point and say hello!"
