Pregnant Gisele Bündchen Hides Baby Bump at Pilates Class in Miami

Gisele Bündchen is keeping fit during her pregnancy … and you can hardly tell she’s got a bun in the oven.

The model was spotted Tuesday for the first time since it was revealed she’s expecting a child with her jiu-jitsu instructor boyfriend Joaquim Valente … hitting up a Pilates class in Miami.

Gisele is doing a pretty good job hiding her baby bump here … mostly shielding her stomach from prying eyes with a large bag, a baggy overshirt and black tights.

Despite the cover-up, we do know Gisele is over halfway through her pregnancy … as we first reported, she’s around 5 or 6 months pregnant.

Gisele’s going to be a mother again at 44, and we’ve always seen her being super active with Joaquim … and it appears she’s sticking to her routine.

The pregnancy came as a shock to some, but as we’ve told you … Gisele gave her ex-husband Tom Brady and their two kids a heads-up before the media found out.
