Emma Bunton's dog is missing – and she needs more than just Girl Power to get her back.
"My gorgeous brown Labrador went missing on daily walk," the Spice Girl Tweeted
on Monday. "She will be so scared please look out around East Barnet, Hadley Wood, Trent Park [areas of London]."
The pooch, named Phoebe, is micro-chipped and described by Bunton as "gentle."
The dog's disappearance has left the singer "in bits," she Tweeted
later. "Thank you for all your reassuring messages! Please keep looking."
