Miranda Lambert Brings Boyfriend to ACM Awards and Blake Shelton's Gonna Be There Too

Miranda Lambert isn't being shy about moving on from Blake Shelton -- she's sticking close to her new boy toy in Las Vegas, where it's likely they'll bump into Blake ... and maybe even Gwen Stefani.

Sources at the Academy of Country Music Awards say Miranda's been parading around singer Anderson East all weekend, and introducing him to everyone as her "boyfriend."

That's not surprising, they've been together for a few months, but It's interesting because her ex, Blake will also be at the ACMs. Far as we can tell, this is the first time she's brought Anderson into a situation like that.

Both Blake and Miranda are scheduled to perform at the award show Sunday ... and we're told there's a chance Gwen will be in the audience supporting her guy.

It's a country song just waiting to happen.
