Gwen Stefani is reportedly pregnant.

The singer is said to be expecting her third child with her rocker spouse Gavin Rossdale. The pair already have sons Kingston, seven, and five-year-old Zuma together and are apparently delighted to be expanding their family.

"Gwen and Gavin couldn't be happier. She’s just trying to focus on resting right now. She wants to make sure that all is well with the baby," an insider told In Touch Weekly magazine.

The couple's representatives are yet to comment on the report.

The 43-year-old singer is known for her stunning figure, which snapped back into shape following her two pregnancies. She is often seen showing off her toned stomach in crop tops, but opted for a flowing black vest when she was spotted in Los Angeles at the end of last month.

Last year, Gwen discussed the impact motherhood had on her. The No Doubt singer admitted worrying about whether she is doing a good enough job, especially as her children are growing up.

"The only thing I really worry about is, again -- like, I keep bringing it up because it's my biggest stress -- how do I do this and that? How do I do both? So that’s like the constant battle that I have every day. I do worry about that all the time,” she previously told UK magazine Elle.

"When you first have a baby your life doesn't change. I mean, you have a little less sleep and you drag these cuddly things around and it's just amazing. But you still get to be you. Once they get to, like, five, six and school, it starts to get, like, ‘Wow, they’ve got real problems. They're my responsibility…' Oh my god. That is overwhelming."
