Pregnancy alert: Gisele Bündchen debuts baby bump in Brazil! (PHOTOS)

Looks like congrats are in order for the world's most famous supermodel. Gisele Bündchen stepped out in her native country of Brazil sporting what looks undeniably like a sweet little baby bump!

Bündchen, 31, showed off her blossoming body when she arrived at the international airport in Rio de Janeiro on Saturday. She hasn't confirmed the pregnancy yet, but she never made a secret of how eager she was to have a big family like her own. She is one of six children!

Bündchen is already mom to Benjamin Rein, 2, with hubby Tom Brady, 34 and step-momma to 4-year-old John Edward Thomas–Brady's son with former flame Bridget Moynahan.

Back in 2007 when baby Benjamin was not even a glimmer in her eye, she told Vanity Fair that she'd be down to raise a big brood. "I'd be lying if I said no – my parents have been married for 35 years and have six children," she gushed. 

Now, it seems she's pregnant with baby number two. Congrats to the supermodel and her happy family!
