Gwen Stefani doesn't want her pregnancy to stop her working.

The singer is expecting her third child with husband Gavin Rossdale but rather than take things easy she is determined to continue with her career as normal.

A source told RadarOnline.com: ''Gwen is working through this and even going to a lot of parties and social functions as if she isn't pregnant at all, and she's not interested in having long conversations with her friends about it either.

''She's clearly trying to be the ultimate low maintenance mom.''

As Gwen has been through two previous pregnancies - with her sons, Kingston, seven, and Zuma, five - she is finding this one a lot easier and seems to be breezing through it.

The source added: ''Everybody is wondering how Gwen is doing it ... When people bring up that she's pregnant, she tries to change the subject - she's definitely trying to do something different with this pregnancy.''

It was revealed in September that Gwen, 44, and Gavin, 48, were expecting another child together.

The No Doubt star previously admitted she finds it a challenger just like all working mothers to find the right balance between her family life and work responsibilities.

She said: ''It's super hard. Every day is a challenge and I don't know, like, it doesn't work most days but some days you get up and it's all good.''
