Are Gwen Stefani and Blake Shelton going on tour together amid rumors of a possible split?

According to a report, Stefani wants Shelton to accompany her on her This is What the Truth Feels Like Tour, which kicks off next month.

“Gwen is worried about the idea of spending so much time apart,” an insider revealed to OK! Magazine on Tuesday. “She’s afraid it’s going to blow up their romance.”

Last year, Stefani and her husband of 13 years, Gavin Rossdale, parted ways and months later, it was revealed that Rossdale had allegedly engaged in an affair with their former nanny. So, it’s no surprise that Gwen has “trust issues” or “wants to keep an eye on Blake,” the source explained.

The source also said that in addition to Stefani reportedly wanting to keep her eye on Stefani, she was convinced that she would see a boost in ticket sales if fans knew he could potentially make an appearance during her shows.

“At this point in their careers, Blake is bigger than Gwen,” the insider explained. “The idea that he could show up to perform their duet would be very attractive to fans.”

Stefani and Shelton began dating at the end of last year just months after Stefani announced her divorce from Rossdale and Shelton announced his split from Miranda Lambert. At the time, Stefani and Shelton were starring alongside one another on the ninth season of The Voice. Since then, they've faced rumors of an engagement.

"Let's just take it one day at a time," Stefani said during an appearance on 94.7 FM's "The Tommy Show" when asked about the chance of an engagement in the near future. "Everything's crazy right now so no, absolutely not."

"Can you imagine the amount of gossip-y, weird stories people make up?" she continued, according to PEOPLE Magazine. "To me, it makes me laugh every day. I actually do Google my name just so I can see the next one that's gonna happen, because it's gotten so out of control. The best part about it is it's hilarious; the worst part about it is that some people actually believe that stuff like that is what's funny."
