Hollywood divorces and romances can be very complicated. Gwen Stefani’s former husband Gavin Rossdale is reportedly unhappy that his children have been spending time with the “No Doubt” singer’s boyfriend Blake Shelton.

A source has shared with E!News that the Bush frontman “doesn’t like” his former wife Stefani bringing their children to hang around “The Voice” coach. Stefani and Rossdale share three children together namely 9-year old Kingston, 7-year old Zuma and 2-year old Apollo.

Several months after the former Hollywood couple announced their plans for divorce in August 2015, romance bloomed between Stefani and Shelton. The two celebrities started dating in October 2015. The country singer has reportedly formed a close relationship with Stefani’s sons and has been spotted spending time with them along with the “Used To Love You” crooner.

The source has also stated that Rossdale “doesn’t agree” with Stefani’s relationship with Shelton. Another insider told E!News that Rossdale would have wanted to work on a possible reconciliation with the No Doubt singer. “If it were up to Gavin he would want to work it out with Gwen,” the insider said.

Meanwhile, the former couple was said to have met secretly to discuss their three children and Stefani’s relationship with the country singer, a source shared with Us Weekly magazine. The secret rendezvous has also been described by the source as an “emotional” meeting between the former husband and wife.

“Gwen had a meeting with Gavin to discuss her relationship with Blake and how it will affect the children going forward. [Gavin] wants to be consulted on everything concerning the kids and the role that Blake is playing in their lives,” the source stated.

Stefani and Rossdale were married for almost 13 years before the two musicians’ separation in 2015. The former couple’s divorce was finalized in April where both share joint custody over their three children.
