Gwen Stefani and her husband Gavin Rossdale may be adding a new addition to their crew of little rock stars. 

According to sources speaking to In Touch Weekly, the 43-year-old mother of two is pregnant with her third child. 

“Gwen and Gavin couldn't be happier," the source shared with the mag. "She's just trying to focus on resting right now. She wants to make sure that all is well with the baby."

Stefani and Rossdale -- who married in 2002 -- already have two sons, Kingston 7, and Zuma, 5. Us Weekly reports that during a recent family vacation to the South of France, the exceptionally fit singer and fashion designer "showed a slight tummy while wearing a pink bikini top and side-tie bottoms." 

On Wednesday, after the news of her pregnancy broke, Stefani was seen wearing a loose-fitting top, the New York Daily News reports.

In an interview with Marie Claire last year, Stefani shared that she wanted to eventually have another child.
