Catty fashion critic Mr Blackwell has just released his latest worst-dressed list, and (quel surprise) new mum Britney Spears has scooped the top 'honour'. Proof, if you needed it, that trailer trash chic is never cool. Mary Kate Olsen doesn't fare much better, coming in second place thanks to her passion for dressing like a homeless person. And then there's Jessica Simpson...oh, where to begin! Here's the 'top' 10 in full.

1. Britney Spears: "When it comes to couture chaos, this tacky terror should take a bow – looks like an over-the-hill Lolita. From the princess of pop to the ultimate fashion flop."
2. Mary Kate Olsen: "In bag lady rags that look depressingly decayed – forget the accessories and buy some Raid."
3. Jessica Simpson: "It's time to sack the stylist and divorce the designer… she resembles a cut-rate Rapunzel slingin' hash in a Vegas diner."
4. Eva Longoria: "Gorgeous face, garish taste… what a waste."
5. Mariah Carey: "The world applauds your musical emancipation… but please – leave that body to our imagination."
6. Paris Hilton: "The Burger Queen Sensation may be very rich – but she looks like yesterday's cheesecake… with a side of kitsch."
7. Anna Nicole Smith: "Queen Kong in cheap lingerie."
8. Shakira: "Coiffure by Medusa… clothes by the Marquis De Sade."
9. Lindsay Lohan: "The Teen Scream defines Fashion Fright – looks like she's aged 30 years overnight."
10. Renee Zellweger: "Runs the gamut from Kewpi Doll Dreck to Red Carpet Wreck… she looks like a painted pumpkin on a pogo stick."
