Earlier this month, ET caught up with RaeLynn on the red carpet at the CMT Artists of the Year Awards, where she gushed about the marriage advice Shelton and his ex-wife, Miranda Lambert, gave her once they heard the exciting news.
RaeLynn has remained close with Shelton after competing with him during season 2 of the singing show, and she's been on the road touring with Lambert.
"I talk to both of them. You know, they're grown-ups. You handle things," she said of her relationship with the former couple. "[They said] 'It's all about when you find the right person, you gotta kinda go with it.' They've both been so supportive."
She also revealed she's a huge fan of Shelton's new relationship with Stefani, saying, "I think it's awesome! I mean, she's Gwen Stefani. They're both great people."
Shelton, 39, and Stefani, 46, were spotted out and about in the Los Angeles area earlier this week before taking off to the Music City. While the No Doubt frontwoman was shopping for Christmas presents in Van Nuys, her beau was seen hanging out with her dad, Dennis Stefani, at her parents' home in Westlake.
