Big Brother star Chanelle Hayes has taken the plunge, dyeing her blonde hair brunette, to look even more like her celebrity idol Posh Spice. Chanelle, 20, revealed her sleek new brunette bob as she ran errands in central London. But unlike her Spice Girl idol, she chose to cover up her assets - albeit in a revealing short black coat, teamed with a pair of fashionable ankle boots and sheer black tights. And with her oversized glasses to complete the look, WAG wannabe Chanelle looked uncannily like her role model Mrs Beckham. Double take: Chanelle pops to the shops in central London revealing her new brunette bob which is just like idol Victoria Beckham's One onlooker said: "Chanelle looked gorgeous but everyone thought she was Victoria Beckham...so sophisticated." Chanelle has long been obsessed with the head WAG and Spice Girl, and has copied her every style move. And now she has followed Posh by reaching for the dye bottle, after the Spice Girl decided to return to her brunette look especially for the groups reunion tour. Wannabe: Posh obsessed Chanelle has copied her idols every style move Chanelle's new look also comes after her traumatic split from former boy band boyfriend Zac (Ziggy) Lichman, 26. Happily single Chanelle said she's embracing the single life following her split from Ziggy, but she recently stormed out of a party when the male model arrived hand in hand with an attractive brunette. Spot the difference: Her new hair colour makes her look uncannily like Mrs Beckham who was herself out shopping in London earlier in the week Chanelle cut her night short as soon as she learned the pair were also at the OK! magazine bash, storming out just moments after she'd stepped onto the red carpet. She said recently: "I'm sick of boys. I'm just going to have fun for a while. Who needs men when you have your girlfriends and cocktails? "Ziggy and I have split for good. I was really upset about the way he ended it. "We all refer to him as Rebecca, after Rebecca Loos, the kiss and-and-tell merchant." But with her new look, clearly Chanelle won't be lacking in unwelcome male attention.
