Posh smirks as she cosies up to dolphin in candid Twitter photo

London, July 2 (ANI): Victoria Beckham, who was slammed for not smiling during her photocall with the Spice Girls last week, has showed she can smile when she wants to, even if it means letting out a subtle grin.

The pic had the fashion designer looking happy, as she cosied up to a dolphin on a day out with her children.

The wife of footballer David Beckham had taken her children to an aquatic park in California so her sons Brooklyn, Romeo and Cruz could swim with dolphins.

And it appears spending time with the beautiful creatures had certainly given Victoria something to smile about.

"Such a special day with the children swimming with dolphins!!! They are so beautiful!!!! x vb," the Daily Mail quoted her as tweeting.

The 38-year-old was maligned by her critics for being the only Spice Girl in the line-up not to smile and also for her apparently distant body language.

Melanie Chisholm, aka Sporty Spice, defended her former bandmate and insisted that the designer was in great form.

"It's annoying when people say Victoria wasn't smiling or didn't want to be there. She really did," she said.

"It was a flying visit and both her and Melanie [B] were exhausted as they'd flown in from Los Angeles. She was so tired but, among us, she was on great form.

"She's a very busy lady and in the middle of designing a new range. It's certainly not easy for her," she said.

Meanwhile, Victoria is preparing for Harper's first birthday party.

The little girl is set to turn one on July 10th and Victoria has apparently splashed out for an extravagant bash. (ANI)
