Miranda Lambert reportedly threw a major shade at Blake Shelton and Gwen Stefani as the country singer reportedly called the whole romance as a "publicity stunt."

Apparently, the country singer-who is said to be dating Sam Hunt-saw the Christmas card sent by the new couple to their friends.

"Miranda caught wind of the card and is just embarrassed for them," the insider told Hollywood Life. "It's just too much and too fast. She thinks it's just a publicity stunt."

"Miranda feels like if they were confident about their relationship, then they wouldn't feel the need to flaunt it so much!" it added of the Gwen Stefani and Blake Shelton romance.

Meanwhile, in another report, Sam Hunt is reportedly going on a getaway and right now, it's not clear if Miranda Lambert is joining her new man.

The two have been rumored to be dating after her divorce from Blake Shelton.

During Thanksgiving, Sam Hunt went home to Cedartown to celebrate the holiday with his family.

"Most of my family all lives pretty close to where my parents live, so it's been nice hanging with them," he said. "It's been long overdue. This year has been so crazy for us, so there is plenty to catch up on around the dinner table!"

For Christmas, Sam Hunt is expected to go back home to Cedartown, and maybe this time he will bring Miranda Lambert as a date?

"The thing is that this will be a boy's trip, so there doesn't seem to be any reason that he would bring Miranda Lambert along with him if the two are dating. Sam is going with his dad and brothers over New Years to enjoy some time on the beach," said Inquisitr.
