Pop songstress Natasha Bedingfield is kicking off her first US tour with Verizon Wireless acting as sponsor and offering all sorts of goodies for fans that use its V CAST service. V CAST users who download Bedingfield's mobile content have a chance to win concert tickets that will be delivered directly to their phones.

During the tour, 20 fans at each concert venue who download Natasha's music, ringtones or ringback tones will win the chance to meet the artist. Other contests and sweepstakes invite fans to submit a 30-second audio or video clip of themselves singing the Bedingfield hit "Pocketful of Sunshine" or co-star in a virtual music video at the show via a giant green screen.
