Gwen Stefani’s three children seem so close to her boyfriend Blake Shelton that they call him “Daddy Blake,” according to a Star magazine report, cited by Hollywood Life. The report comes after Shelton and Stefani’s engagement rumors began to swirl amid her pregnancy and miscarriage gossip.

“The moment Blake walks through the door, those kids are climbing all over him like it’s a WWE tournament,” a source told Star magazine, according to Hollywood Life. “He’s so incredible with her kids, taking them on dune-buggy rides and playing games like laser tag. You’d think he’d raised a football team of rowdy boys!”

“Everyone knows Blake is a big kid, so it’s no surprise that they adore him. And he loves those boys just as much as he loves their mother,” the insider reportedly told the gossip magazine.

However, the report is unlikely to be true and Gossip Cop debunked the Star magazine rumor. The gossip debunking website called the report “irresponsible” and “untrue.”

Stefani recently released a new song “Make Me Like You,” which is about Shelton, and following this Shelton released brand new single “Came Here to Forget” about Stefani and his separation from Miranda Lambert. In a statement, Shelton said the song was his “most intimate yet,” Entertainment Weekly reported. The song was written by Craig Wiseman and Deric Ruttan.
