A little more than two months ago, Gwen Stefani was strolling around with her flat-as-a-pancake midriff on display. But in recent days, she's developed a fondness for tent-like tops, a personal trend that has inevitably led to talk that the popster, 43, is expecting her third child with husband Gavin Rossdale, 47.

"It's very new, and they just found out," a spy tells Us. "They're excited!"

Another insider echoes the ostensible bun-in-the-oven news to E!, with a source enthusing to In Touch, "She and Gavin couldn't be happier."

The couple are already parents to sons (and fashion plates) Kingston, 7, and Zuma, 5.

Last year, Stefani opened up about their attempts to add to their brood.

"I really, really, really wanted one about two years ago. And it didn't really work out," she told Marie Claire, without elaborating. "So ... I feel good with what we've got. Everything works out how it should. You can't plan anything, right? You can try."

She bubbled to Vogue that it's "superfun being a mom, but it's not what you think it's going to be. And it's really gradual. At first, your life is totally the same. You have this cute little thing that you get to drive around everywhere and you're so proud and it's amazing. And as they grow older, it really does start to change your life. Like, 'Oh, my God, they have school, they have to get through first grade, they have to learn to read.'"
