Fans at Luke Bryan’s recent Crash My Playa festival in Mexico may have been surprised when Blake Shelton’s girlfriend, Gwen Stefani, showed up to play a few songs, but Luke says Gwen is actually at ease the country crowd. Bryan tells People, “I think Gwen enjoys learning a little bit more about us country people! But she totally fits in and has a blast.” Luke adds that he’s glad that Blake and Gwen could make out for the festival and “have the ability to enjoy themselves.”
