Christina Aguilera says the 'Voice' coaches are like "brothers" to her but Adam Levine thinks they are more like her children.
Aguilera - who has children Max, seven, from her marriage to Jordan Bratman,and five-month-old Summer with fiance Matthew Rutler - is thrilled to be back on the show after her maternity leave and says seeing Adam Levine and Blake Shelton again, as well as Pharrell Williams, who joined while she was on her break, is like "coming home".
She said: "It's always fun coming back to the show. It's like, you know, these guys are like brothers.
"It's like coming home to a very oddly dysfunctional, awesome family! They keep me laughing! I honestly don't know what I would do if I came back and Blake and Adam were not here because I would get so bored probably."
While Christina - who says there is a nursery on set to care for her children - views the coaches as her brothers, they see themselves as more like her children.
Adam joked to 'Entertainment Tonight': "There's a nursery for me and Blake too. She actually has four kids, if you include myself and Blake."
Meanwhile, Pharrell is convinced the Maroon 5 star and his country singer panellist pal should make a movie together.
He said: "When the cameras are off, [Blake] is a full on comedian. I'm just wondering about one day there will be an Adam and Blake movie."
