We spotted Gwen Stefani paying a visit to the doctor, on Thursday, amid rumors that the singer is pregnant with her third child. While her publicist still has not confirmed the pregnancy, many outlets have reported the news. Despite the dressed-down style -- we think the singer is positively glowing!

Appearing healthy and happy, Stefani was photographed in the parking lot of a Los Angeles hospital for what is believed to be a doctor's check up.

Since news the 43-year-old and hubby Gavin Rossdale were expecting, we've noticed that No Doubt singer has been rocking some suspiciously loose clothes -- and today's oversized ensemble is no exception. Is it to mask her growing baby bump? We think so!
