Rowland appeared to have spilled the beans about the unborn bundle's sex during a recent impromptu interview with US Weekly at the Cosmopolitan Awards in Britain earlier this week.
When an US correspondent asked about buying the new baby a shower present, Rowland gushed: "I think her dad is going to give her everything anyways. All I can give her is love."
The Web site Too Fab observed Saturday Rowland's statements about her former Destiny's Child mate were significant since the pop power couple has adamantly refused to say if a boy or girl is on the way.
But Rowland's statements didn't appear to be a slip of the tongue. She went on to dismiss concerns about the little princess becoming spoiled. "I think she'll be very well behaved," she opined. "Her parents will make sure of that."
