HollywoodLife previously reported that the country singer was not in a hurry to propose to Stefani. A source told the gossip website, "Blake and Gwen are no longer in the honeymoon phase of their relationship, but they still love each other very much and are very happy with each other."

The website added that The Voice judges were not planning a wedding anytime soon, as the source added, "And an engagement or wedding will not change that, so they aren't rushing into any of that. So a real honeymoon isn't on the horizon anytime soon. They are happy with their current status of being boyfriend and girlfriend."

The Came Here To Forget singer was previously married to Miranda Lambert for four years, while Stefani was married to Gavin Rossdale for 13 years and shares three children – Kingston, 10, Zuma, 8, and Apollo, 3 – with him.
