According to the tabloid media, Miranda Lambert is up to no good. Even though she pulled the plug on her marriage to Blake Shelton last summer, there's a new report that says she's absolutely devastated with the news that he's moving on so fast with his current girlfriend, Gwen Stefani. In fact, there are rumors that even say she's trying to block the couple's upcoming $2 million dollar wedding.

According to Celebrity Dirty Laundry on Sunday, Blake and Gwen are planning quite the party that is going to cost them a pretty penny. Even though they are looking to have a small-town, close-knit "backyard potluck theme" wedding, it will be packed with VIPs from Hollywood, Nashville and Europe.

What's more, Blake is trying his best to keep their wedding plans underwraps as he's afraid that his ex-wife might pull something up her sleeve if she finds out about their big day. Miranda is supposedly not only upset about Gwen dating her ex-husband, but she also thinks that the singer is single-white-femaling her to a certain extent, too.

Blogger Grace Gerard writes, "Miranda Lambert is fuming as Gwen reportedly has already settled in and is redecorating Blake's Oklahoma home. Not only does Miranda allegedly think that Gwen stole Blake while they were still married but now the interloper is stealing her country style as well!"

So far, neither Blake nor Gwen have made any comments about the report. The couple started dating only a few months after Blake and Miranda called it quits. At the same time, Gwen pulled the plug on her decade-long marriage to her ex Gavin Rossdale, too.
