Gwen Stefani is reportedly pregnant and expecting her third child with husband Gavin Rossdale. The 43-year old, who is also the mother of two sons Kingston, 7, and Zuma, 5, is said to be ecstatic about the news.

According to In Touch Weekly magazine, a source revealed, "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."

Stefani came to fame with songs made with the group No Doubt and has since seen success as solo artist. The "Cool" singer is also famous for flaunting the washboard abs on her slender physique.

However, as of lately, the "Rich Girl" artist has been trading in her crop tops for long shirts that cover her stomach and possibly a baby bump.

According to the Daily Mail, Stefani was last spotted on August 29th and sported a covered up look compared to her usual baring of flesh. The singer wore a long baggy black top, loose white pants, and black biker boots.

Back in September of last year Stefani told Marie Claire magazine that she and Gavin Rossdale had tried for a third child in 2010, but it did not work out.

She confessed, "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 also admitted to Vogue that she had no idea how much having children would forever change her. She explained that "It's super fun being a mom, but it's not what you think it's going to be. At first, your life is totally the same. 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.' It starts getting so serious, and you're like, 'Aaaaaaah!'"
