Gwen Stefani — mother of three — wants to have a baby with boyfriend Blake Shelton after seeing his interactions with her three sons, Life & Style magazine reported Monday. The report comes amid growing rumors that the couple is planning to get married over Christmas.

“She loves that he’s such a family man,” a source told Life & Style. “Seeing Blake with her kids just makes Gwen fall in love with him even more.”

“They’re actively trying to start a family,” another insider told the magazine. “They’ve never been happier or more in love.”

Stefani, who turned 47 on Monday, has three sons with ex-husband Gavin Rossdale — Kingston, 10, Zuma, 8, and Apollo, 2. She does not mind being pregnant when the two exchange vows later this year, according to the magazine.

Stefani has “no problem walking down the aisle while pregnant,” the magazine had reported on Sunday, citing a source. “She sees how amazing Blake is with her kids and she told him she wants to give him his own child.”

The “Hollaback Girl” singer is also looking into all options to get pregnant with Shelton.

“She has incredible doctors and she’s explored all her options, including surrogates,” an insider reportedly said. “No matter what, Gwen wants the child to be hers and Blake’s baby together. She’s ready.”
