“It’s total bulls—,” says a source of Shelton. “There’s nothing there. They’re nothing more than friends.”
But the two do have a fun rapport on The Voice (airing Mondays and Tuesdays at 8 p.m. EST) and have bonded on set with the rest of the cast.
“I don’t think anybody’s more covered up than Gwen, from just raising three boys and balancing a TV show and a solo record or a No Doubt record and touring and her clothing line,” Shelton, 39, told PEOPLE earlier this summer. “Every day in the compound, you see her having a meeting with people you’ve never seen her having a meeting with before. It’s crazy.”
Says Stefani, 46, (who announced her split from Gavin Rossdale in August; Shelton and Miranda Lambert announced their divorce in July) of becoming fast friends with Shelton: “He’s such a fun, funny guy. He just seems like such a good person. I love being around him.”
For now, the country singer is not quite ready to date and is “focusing on himself,” says the source. “He’s open to another relationship in the future, but just not now.”
