Their romance seems to be real and happy, but a new report suggests that Gwen Stefani is actually devastated after discovering texts between Blake Shelton and ex-wife Miranda Lambert.

Miranda Lambert Calls Blake Shelton & Gwen Stefani's Romance A Publicity Stunt

According to In Touch Weekly, during a recent incident backstage on The Voice, Shelton was called away and left his phone behind--when a text from Lambert came through, causing Stefani to flip out.

"Gwen saw it and lost it. She found Blake and asked to speak to him privately, but he said he couldn't right then and there," a source told the magazine. "She had tears running down her face and went and locked herself in her dressing room."

Not long after, she reportedly discovered he was texting Lambert back.

It's not the first time this has caused trouble for the new couple, with another incident allegedly occurring the night they went public at the CMA Awards, when another text from Miranda popped up.

"Gwen saw it," the source said. "Miranda was trying to get Blake to go and see her and her friends at an afterparty."

It also came when Miranda had asked if "they could sit by each other at the CMA Awards. But he declined and asked her to stop texting him," the source added.

However, despite Shelton's assurances that he doesn't want to get back with his ex and is crazy about Stefani, the issue hits home with her because she discovered her former husband, Gavin Rossdale, had been cheating on her with their nanny after she discovered their inappropriate texts.
