Gisele Bündchen Back in Action in Her Underwear

Supermodel makes her return to the runway during Brazil's Fashion Week just six months after birthing baby Benjamin

The catwalk just got a little sexier again.

This weekend, supermodel mama Gisele Bündchen stalked the Colcci catwalk at Brazil Fashion Week in São Paolo, marking her first runway strut since birthing baby Benjamin six months ago.

After the first postpreggers fashion shoots, followed by the requisite adorable mother-and-child naked baby shot in Vogue, this latest gig was the final fashion frontier Gisele had to reconquer. With her mile-long gams all glossy and sexy, the svelte babe showed off the fashion house's sheer tops and black-and-white printed pieces.

Obvs, the lady's back in fine form!
