Blake Shelton and Gwen Stefani reportedly have one topic that is off-limits during “The Voice” shoots -- their respective divorces. Shelton and Stefani, who are rumored to be dating, had announced their divorces early this year.

“Blake doesn’t really bring his divorce talk to her; he tries to make the day on set fun by telling jokes and being a goofball,” a source told Hollywood Life, adding: “It’s more important for him that everyone is in a good mood. No drama!”

The source also said: “Blake loves talking to Gwen and talking to her about music and everything else, except divorce talk. ... Blake doesn’t like talking about divorce because it gets him to think about his divorce, and he wants to move forward instead of backwards.”

Shelton and Miranda Lambert announced their divorce in July, while Stefani announced her divorce with Gavin Rossdale in August. Since then, Shelton and Stefani have been seen together a lot. Although both of them have denied dating each other, a report Monday said the “Sweet Escape” singer was flirting with Shelton and was thrilled that her divorce proceedings were moving smoothly.

“It was heartbreaking and is still heartbreaking going through this whole process, but the fact that Gavin has been very adult in settling everything between the two and really been a man about it has been very therapeutic for Gwen’s healing,” a source told Hollywood Life on Monday, adding: “She looks at this easy divorce with little drama being the best possible scenario to finally move on with her life.”

Stefani had also posted a photo with “The Voice” coach late Monday on Twitter, which had received over 1,500 likes.

Stefani married Rossdale in 2002 and announced their divorce after 13 years of marriage. Both of them have applied for joint custody over their three children -- 9-year-old Kingston, 7-year-old Zuma, and 17-month-old Apollo.
