While the romance of rumored pregnant Gwen Stefani and Blake Shelton has been making headlines since the former's admission that they are "officially" together, Miranda Lambert was reportedly "embarrassed for them."

According to Hollywood Life, the 32-year-old "Bring Me Down" singer felt that there is no reason for her to continuously feel broken-hearted with the highly-publicized relationship of "The Voice" coaches.

Amid the various reports of the new couple's public displays of affection, whether on-cam or off-cam, a source of the outlet revealed that "Miranda caught wind of the card and is just embarrassed for them."

"It's just too much and too fast," the source added about Miranda Lambert's take on the relationship of ex-husband Blake Shelton to Gwent Stefani who has been rumored to be pregnant with the 39-year-old country star's baby. "She thinks it's just a publicity stunt."

The unnamed informant further narrated that "The House That Built Me" singer's doubts allegedly rooted from the too much PDAs of the "Bringing Back the Sunshine" crooner and former "No Doubt" lead vocalist.

"Miranda feels like if they were confident about their relationship, then they wouldn't feel the need to flaunt it so much!" the insider dished.

In the meantime, Gossip Cop has just debunked the rumors that Gwen Stefani is pregnant and expecting a baby with Miranda Lambert's ex Blake Shelton, as what "In Touch" magazine previously reported.

"Blake Shelton and Gwen Stefani are NOT making baby plans, despite a new tabloid report," the site pointed out. "Gossip Cop can exclusively bust this story. We're told it's 'not true.'"

Based on the report of the magazine, a source claimed that the "Doin' What She Likes" singer "would love to have a baby" with his new girlfriend and that the latter "always wanted a daughter."

Accordingly, a rep for Miranda Lambert's ex Blake Shelton has personally denied the rumor that Gwen Stefani is pregnant.
