Posh's outfit makes her bottom look huge

Victoria Beckham shocked fans at a Spice Girls concert last week when she stepped on stage looking like she’d grown a bum overnight.

Despite being stick-thin, the 33-year-old was snapped with a huge bottom at the gig at Boston’s TD Banknorth Garden.

The silver sequin-covered corset and matching leggings made for an unflattering fit.

Victoria’s usually pert bot appeared to have ballooned.

Meanwhile, Posh has admitted that she was behind the Spice Girls’ decision to cut short their world tour.

She wants to focus on her fashion line and confesses that she only agreed to get back on stage to show sons Brooklyn, 8, Romeo, 5, and 2-year-old Cruz what she did before she became a mum.

‘I was very nervous about going back into the Spice Girls because I didn’t want to send out a confused message,’ she tells the News Of The World.

‘The reason I decided to do the tour was to show my kids that mummy was a pop star once. I’ve been thinking about this for a long time. I’m not in the music industry any more. I’m in the fashion industry.

‘I’m putting together a team of people now so it will be my main project when I finish this tour in a month.’
