And the supermom award goes to: Victoria Beckham.

Mrs. Beckham really dashed back to Los Angeles just put her daughter, Harper, to bed. The fashion designer was present in a new musical launch for "Viva Forever" with the other members of the Spice Girls namely Melanie Brown, Geri Halliwell, Emma Bunton and Melanie Chisholm. However, "Posh Spice" left the press conference early and she no longer had the chance to bond with her girl friends because of her maternal responsibilities.

"I'd love to stay and hang out with the girls but I'm desperate to see her before she goes to bed. I have to race home for bedtime," Victoria said. Well, she really did and because of that, the singer-turned-designer looked somber as she returned to the United States.

Her one day whirlwind visit to London and her immediate flight back to Los Angeles gave the dedicated mother of four a completely tired and glum appearance as she walked through the airport with her head bowed down. Victoria was dressed in all-black and she was clearly not in the mood to talk to anyone.

While Victoria quickly returned home to the United States, the other Spice Girls members spent the night out in London and had a good time. Melanie Brown enjoyed dinner with her husband Stephen Belafonte at Nobu restaurant. Emma and Geri were spotted partying together at Little House in Mayfair but Mel C was nowhere to be seen.

Victoria Beckham gladly spoke about the upcoming musical show which will open in December at London's Piccadilly Theater.

"London is a great starting point. We're all so proud to be British. We're hopeful this will be the start of something big," Victoria said. "Viva Forever" is a musical based on the hit songs of the group Spice Girls which is written and produced by Jennifer Saunders and Judy Craymer. Victoria Beckham is really hoping for the show's success by becoming a certified worldwide hit.
