Baby on board, indeed! Gisele Bundchen took an afternoon stroll during a Costa Rican getaway on Friday, July 26, with a prominent accessory strapped across her body -- a baby carrier with daughter Vivan, 7 months, happily sugared inside.

The Brazilian supermodel, 33, wore a tiny leopard-print bikini for her beachside outing, with a large floppy hat and oversized shades to keep her face protected from the sun. Baby Vivian similarly wore a large white hat that kept her tiny head cool.

Later on in the day, Bundchen made a splash in the surf, showing off her enviable figure as part of her extended birthday celebration. 

"Thank you all for thinking of me and sending love and birthday wishes," she tweeted on Saturday, July 20. 

The second-time mom (Bundchen also has son Benjamin, 3, with husband Tom Brady) hasn't been shy about sharing her strong mother-daughter bond either. Earlier this month, Bundchen posted a sweet snapshot of herself snuggling up to Vivian with the caption "the best love in the world!"
