In between snippets of concert performances in Katy Perry: Part of Me, Katy Perry has dropped one hint after another about the rise and fall of her marriage to Russell Brand during her massive 2011 tour including their disagreements over starting a family. In one backstage scene of the documentary, Brand texts Perry a picture from McDonald’s and jokes that they should name their child Ronald. But a few minutes later, the Wide Awake singer admits that babies are definitely not on her immediate agenda. “A baby can’t have a baby — and I’m still a baby,” Us Weekly quoted her as saying. A source close to the British comedian has confirmed that children were a sore spot for the couple, who called it quits after just 14 months of marriage last December. “Russell feels there’s no point in being married if you don’t have kids,” the source said.
