Miranda Kerr kicked off the Gillette Venus Step Up & Step Out Summer Tour at Times Square in New York City on June Tuesday. The model looked lovely in a bright yellow lace dress paired with black pumps and bright red lipstick.

Earlier this week, the Victoria's Secret siren posted a photo on Instagram of herself doing a back bend at the beach in nothing but a bikini. It was accompanied by another bikini-clad image and a topless pic.

The photo shoot was for her Kora Organics skincare line.

Kerr is not a topless posing newbie. She showed a breast in Vogue Italia's 2010 3D issue.

The sexy 30-year-old is married to actor Orlando Bloom, and they have a son together.
