Heidi Klum shirt silk shirt sunglasses soccer pregnancy

Is another baby on the way?! Just a day after showing off what appears to be a growing bump, supermodel Heidi "Baby Maker" Klum wore an oversized tunic and hid her belly. The Project Runway host was spotted hanging out wearing some seriously loose clothing while watching her son's soccer game with her children and boyfriend/bodyguard Martin Kristen in Los Angeles on Sunday.

We have to be honest -- we think the star's outfit tiger-rific looks like one of the animal-emblazoned blankets that people sell outside gas stations in seedy neighborhoods. It's not our favorite look from the style maker. But it's definitely clear she is hiding her famed body under the baggy ensemble.

If Klum is pregnant, this would be her fifth child and her first with her current beau. The German beauty has one daughter, Leni, with Flavio Briatore, and three children, Henry, Johan and Lou, with former husband Seal.

Pregnancy rumors were ignited during a family trip to Michaels on Saturday, when the 40-year-old was snapped wearing a sexy tank that showed off the normally fit supermodel's apparent belly.

Klum and Kristen have been dating about a year now, and the two began their romance about nine months after her split from Seal in 2012. The duo have been seemingly inseparable in recent months -- which makes us think that there really is something to this bizarre employer/employee love affair.

Is the next step a baby?! We don't know, but we do know this: the only thing that woman loves more than high fashion is being preggers!
