Fergie wraps all her clothes in plastic because her wardrobe is her "life". 
The 'Big Girls Don't Cry' singer says she is extra careful looking after all her outfits when she is travelling on the road.
She explained: "I pack everything in plastic. I take it quite seriously I suppose - I have to though, because this is my life, wrapped in plastic. My life is on the road."
The Black Eyed Peas star also revealed one of her favourite pastimes is separating her wardrobe into categories.
She added: "Fashion has always been like fancy dress to me, it's always been like playing. I travel so much that I'm always playing with clothes. I spread them out over the bed in whatever hotel I'm staying in, and spend time separating them into categories."
Fergie, 32, recently revealed she and her actor boyfriend Josh Duhamel use a webcam to keep their sex life hot when she is away on tour.
The 'My Humps' singer said: "We're learning iCam. I've actually gotten to see a lot more of him lately, ever since I got home from tour, which is great."
