Blake Shelton, Gwen Stefani Start To Become Family! 'The Voice' Coaches Bond With 'Used To Love' Singer's Son

Blake Shelton bonded with girlfriend Gwen Stefani and her son, Apollo, as "The Voice" judges took lunch at the Loteria Grill in Studio City, Los Angeles on Thursday.

"The mom of three donned an olive-colored jacket with cropped jeans, which featured a sparkling embellishment near the hem," reported Daily Mail.

"The blonde beauty, who wore her golden locks loose with a side part, rocked her signature red lips, pairing it with a matching handbag."

Gwen Stefani's fashion style has not rubbed off on boyfriend Blake Shelton as Miranda Lambert's ex was still wearing his usual plain shirt, trucker's hat and a pair of denims.

"The Voice" co-judges and couple went public with their relationship after the Halloween, weeks after denying a romance between them. They divorced their respective spouses, Miranda Lambert and Gavin Rossdale, earlier this year.

It seemed that Blake Shelton and Gwen Stefani are taking their relationship to another level following the report that the No Doubt singer introduced the country singer to her family.

"On a recent trip to his home in Tishomingo, Oklahoma, the country singer, 39, introduced his girlfriend to the most important woman in his life, his mom Dorothy, multiple sources confirm to PEOPLE," said People. "Then, Thursday, Shelton spent time in L.A. with Stefani's dad, Dennis."

And Blake Shelton was a hit among girlfriend Gwen Stefani's family.

"Blake helped Gwen's dad around the house," the source claimed. "They seemed very friendly and like they were getting along great."

As for Blake Shelton's mom, Dorothy, she reportedly "adores" Gwen Stefani.

"She gave her son two thumbs up on his new girlfriend and as a gift Dorothy gave Gwen a photo of Blake when he was a little boy holding his pet frog," Hollywood Life alleged. "She told Gwen a bunch of stories about Blake's childhood and how he used to save all the wild animals and bring her frogs."
