While Gwen Stefani has yet to address the pregnancy rumors, she was spotted flaunting her small baby bump in oversized clothing on Wednesday. 

The singer covered up her stomach in black loose tee and flowing pants while taking her son to school on Sept. 4. She was spotted and photographed in Los Angeles for the first time since news of her pregnancy broke.

She dressed up her look with stylish heels.

This will be the third child for Stefani and husband, Gavin Rossdale. The couple already has two sons, 5-year-old Zuma and 7-year-old Kingston. 

"[Gwen] and Gavin couldn't be happier" about their exciting news, a source close to the couple told In Touch Weekly on Sept. 4. "She's in the early stages, and she's having a hard time with morning sickness."

"She's just trying to focus on resting right now," the source told the publication. "She wants to make sure that all is well with the baby."

In a September 2012 interview with Marie Claire magazine, Stefani also revealed that she and her husband had tried for a third child in 2010, but it didnt work out.

"I really, really, really wanted one about two years ago. And it didn't really work out. 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 said. 

Speaking with Vogue magazine, Stefani admitted that she underestimated how much children would change her life. 

Enstars reported yesterday that the Stefani and Rossdale were rumored to be splitting, after they fought "nonstop" and attended couples counseling in the hopes of saving their 10-year marriage.
