She may be pregnant with baby No. 2, but Gisele Bundchen still knows how to work it in a bikini!

The word's richest supermodel flaunted a tiny baby bump while hanging on the beach with son Benjamin and their pet pooch in her native Costa Rica, on Monday afternoon, where she's in town to film a new TV ad for her C&A clothing line.

Meanwhile the 5'11 stunner and her New England Patriots quarterback hubby, Tom Brady, have finally sold their two-story limestone mansion located on the famed Beacon Street in Boston for $9.2 million, after three years on the market.

The gorgeous pair are currently settling into their brand new 22,000-square foot $20 million dream home, which was built with eco-friendly materials and boasts waste reduction and recycling programs, and energy-efficient appliances.

Life's clearly a beach for Gisele!
