Miranda Lambert and Gwen Stefani are not necessarily best friends. In fact, there are rumors that the two women hate each other.

In its Jan. 3 issue, Globe claimed that Blake Shelton’s ex-wife hates everything about Stefani. And she’s not scared to let her feelings be known to the rest of the world.

“Miranda has a lot of opinions about Gwen. Let’s just say, she’s not a fan. She’s careful not to say anything about Gwen in public – she doesn’t want the drama. But with friends, she’ll comment on everything about Gwen, including her figure. Miranda isn’t shy about making it clear that she prefers her hourglass shape to Gwen’s pin-thin body,” the source said.

The insider added that Lambert isn’t conscious of what she eats because she’s not also conscious about the way she looks. Stefani, on the other hand, has a lot of restrictions because she’s scared to pack on some pounds.

Lambert is also, allegedly, still upset with Shelton for leaving him and for being with Stefani. So, at any given chance that she can hurt her ex-husband’s feelings, she would and this usually includes making snide comments about Stefani.

“Privately, she snickers at Gwen for looking like she doesn’t eat more than a few field greens a day,” the source said.

This isn’t the first time that Lambert and Stefani were pitted against each other.

Last year, OK! magazine accused Lambert of throwing shade at Stefani and Lambert during one of her live performances. And on another occasion, the country singer was accused of not wanting to perform at an event because Shelton was also there.

In the same year, Lambert was rumored to have thrown digs at Stefani because of what she wore to the Country Music Academy Awards.

However, none of these claims have been proven to be true. In fact, Stefani and Lambert have not even encountered each other and they have not also talked about each other during their interviews.

There’s also no animosity between Lambert and Shelton, who split years ago. And according to reports, Lambert was the one that left Shelton and cheated on him and not the other way around.

As for Shelton and Stefani, the couple couldn’t be more thrilled that they found each other. And it’s unlikely for them to be interested in Lambert because they now have their own lives.
