The country star "has been having a lot of fun" with Stefani's three sons, a source tells PEOPLE
With his boisterous personality, it’s no surprise Blake Shelton and Gwen Stefani‘s sons have become fast friends.
“Blake loves kids and has been having a lot of fun when he spends time with Gwen’s kids,” says a source close to the couple about Shelton’s bond with Stefani’s sons (with ex Gavin Rossdale) – Kingston, 9, Zuma, 7, and Apollo, 22 months. “They adore him.”
Since stepping out as an official couple in November, The Voice coaches “have spent a lot of time together and with her family,” says the source.
But while the two have become more serious (Shelton recently took Stefani back home to Oklahoma to meet his mom, sources confirm), they’re still taking things one step at a time.
“They’re just having fun and enjoying each other,” says the source. “There’s no pressure. They’ve been able to support and relate to each other and have gotten through a very difficult and now triumphant time in their lives.”
