Talk about one hot mama! Gisele Bündchen stepped out for a walk on the beach with her younger sister Rafaela (below) in Costa Rica earlier this week, and the siblings were quite a sight to see. The pair both rocked black bikinis for their stroll on the sand, flaunting their toned physiques as they enjoyed some relaxing family time.

Bündchen's enviable figure isn't the only thing the supermodel has to celebrate—her daughter with husband Tom Brady, Vivian Lake, turned two-years-old today. The proud mother shared an adorable throwback snap of her and baby Vivi on Instagram this morning to commemorate the milestone. "I can’t believe my little girl is turning 2 already! Thank you for being my little sunshine. I love you so much," she captioned the sweet photo (below).
