Fergie Bucks Pregnancy Rumors at the Rodeo?

So did we speak too soon on Fergie after those billowy dress photos? Or are these still ambiguous considering how crazy flat her stomach usually is? Or am I overthinking this and she just looks super cute performing at the rodeo in Houston last night? I can't decide! Judging from those photos yesterday you all seemed to think she looked pregs but after seeing these, she looks decidedly less so. Hmm, what do you think?
