Gwen Stefani's having trouble selling tickets for tour

Gwen Stefani’s love life may be rocking and rolling with Blake Shelton, but her supposed comeback tour has hit a stumbling block.

In Touch magazine reports that the Misery singer is struggling to fill seats on her upcoming This Is What the Truth Feels Like tour. “Her tour kicks off July 12 in Massachusetts and only 5,000 tickets have been sold in a venue that holds 18,000 — and that was after the huge promotion in which her tickets were being sold discounted on Groupon,” a source tells In Touch.

The Voice coach is set to play the Perfect Vodka Amphitheatre in West Palm Beach on July 27. A quick scan shows many seats still available at that venue as of press time. “In the ’90s, when she was with No Doubt, she’d sell out stadiums all the time,” the insider adds.
