The songstress is rumoured to be expecting her third child with husband Gavin Rossdale and has been keeping us guessing by sporting a number of baggy outfits and layered ensembles, which conceal her tummy.
However, on Tuesday (5 November) Gwen decided to wear a fitted grey T-shirt and it looks as though there is a pretty obvious baby bump hiding under there!
She teamed her casual top with a tartan bomber jacket that featured leather sleeves and a pair of dark jeans, while walking holding on to her youngest son Zuma's hand.
Gwen, 44, also opted for a pair of heeled Dr Martens boots, as opposed to some practical flats, like the ones she was seen wearing at a baby shower last weekend.
If she is indeed pregnant, it seems Gwen isn't compromising on her cool and edgy footwear!
The No Doubt star and her hubby Gavin have yet to comment on the increasing speculation that they are set to become parents for a third time.
But the couple haven't let the numerous rumours stop them from socialising as normal.
Although they may not want to confirm whether a baby is on the way, Gwen and Gavin have still mingled with their fellow stars at a number of events recently, including a gala in Beverly Hills last month.
The couple are already parents to sons Zuma and Kingston.
