Victoria Beckham has hit out at critcs who keep branding her 'miserable'. Posh says she is just a working mum, surviving on little sleep since the arrival of her baby daughter, Harper Seven.

Posh launched her latest fashion collection recently at London's Harvey Nichols department store (pictured) and received critical acclaim for her new designs but she admits that being a career mother is "tough."

"If people want to say I'm miserable, so be it," Posh told a reporter. "I'm really not. I have a lot on my plate. I'm not going to lie about it. I'm really tired but I'm also very happy with my life. I'm basically just like any woman who is working and has lots of children. It's tough."

Victoria, 37, said that Harper Seven was not sleeping well and had left her desperate for a good night's sleep. "I'm up with the baby as all mums are," said Posh. "And I wouldn't have it any other way. There's not a team doing it for me. And then people want to say I look s**t. Well, I'm a working mum, so give me a break."
