Us Weekly reports Gwen Stefani of No Doubt and her husband Gavin Rossdale of Bush visited Kitson boutique in Los Angeles on March 27th to see how well her L.A.M.B. line of clothing was selling. “We told her it was flying off the shelves,” said owner Fraser Ross. “Gavin was so proud of her.” Days later, the pair were hand-in-hand at Prince’s sold-out opening night tour at the Staples Center. Meanwhile, the couple are continuing their efforts to have a baby, so far to no success. “But Gwen says, ‘We’re trying really hard,” according to a pal.
