New York Fashion Week is not for the weak!

Victoria Beckham has been burning the midnight oil to prep for her eponymous clothing line's upcoming runway show at New York's Lincoln Center.

But on Friday, the Spice Girl and mother of four -- notorious for her reluctance to crack a smile -- admitted to her nearly 4.5 million Twitter followers, humorously, that she's feeling a little punch drunk.

"After three hours sleep I feel like an old bag!" Beckham, 38, wrote beneath a hilarious photo, in which she works at a laptop with a giant handbag over her famous head.

She managed to escape her studio on Thursday to attend some Fashion's Night Out festivities in the Big Apple, but the excursion cost her some valuable time. "It's going to be a late night, still in fittings!"

Beckham (who reunited with her Spice Girls bandmates last month for an unforgettable reunion performance at the Closing Games for the London Olympics) opened up to the New York Times about her flourishing career as a fashion designer.

“In a very humble way, I always had big dreams and ambitions for my brand,” she said, adding that she wants to take the Victoria Beckham brand “from America to the rest of the world."
