Miranda Lambert, Blake Shelton's wife, is not happy and the rumor is her unhappiness is with Blake's fellow "The Voice" coach Christina Aguilera.

I heard from a reliable Nashville source this week that there are rumors that Miranda Lambert doesn't like Christina Aguilera flirting with Blake Shelton. Last year, during the first season of "The Voice they had quite a twitter feud going.

Christina doesn't follow Miranda on twitter but she did send this tweet to Blake,

"@blakeshelton Now we need to team up for a country duet Blake!! I'm down!! Let's go!"

She had a big hit with Adam Levine and Maroon 5 already, so why not a hit on Country radio? Pop star Kelly Clarkson had a huge Country hit with Jason Aldean.
Hmmm, do I smell the beginning of a Kelly Clarkson/Christina Aguilera twitter feud?
Check out what Blake has to say about Christina and her...assets.
