After being scrutinized for not smiling in even a single photo during the "Spice Girls" photocall last week, Posh proves that she smiles.

Victoria Beckham shows that she does smile, that is when she wants to. Posh recently posted a photo of herself with a dolphin on her Twitter account. Probably to prove to everyone that she is capable of smiling.

Last week, Victoria Beckham flew in to London to be with the other "Spice Girls" member for the launching of the "Viva Forever" musical. Victoria was criticized for being the only girl who did not smile amidst the many photos produced during the photo session. Her body language also indicates a certain level of discomfort.

Later on after the photocall, she flew back to Los Angeles instead of spending time with the girls. But even if Victoria was judged by her critics, another band member, Melanie B. defended Posh.

"It's annoying when people say Victoria wasn't smiling or didn't want to be there. She really did," Mel B. said. "She's a very busy lady and in the middle of designing a new range. It's certainly not easy for her."

Along with the recent photo of her "slightly" smiling, she captioned, "Such a special day with the children swimming with dolphins!!! They are so beautiful!!!! x vb"

Victoria is back in California ad took her children, Brooklyn, Romeo and Cruz to an aquatic park to swim with the dolphins. She is also busy preparing for Harper's first birthday celebration.

"The garden will be filled with big pink cuddly toys, pony rides, a bouncy castle, balloons and tons of cupcakes. It'll be totally pink," a source told Closer magazine that Victoria splashed out on her daughter's first birthday party. "It sounds odd, but she's even hiring special dyed-pink rabbits."
