Adriana Lima and Erin Heatherton Promote VS Fitness Line

Angels Adriana Lima and Erin Heatherton kicked off the launch party for Victoria's Secret's new fitness line at NYC's Herald Square on Tuesday. The fiercely fit models showed off the brand's latest gear with right-hooks, jabs and a display of their fun personalities. During the event, Erin shared a picture of Adriana on Instagram "showing her how it's done" as she taped Erin into a sparkling black pair boxing gloves and the two sparred in style. This is the girls' second modelling stint together this month after they also teamed up to take on the catwalk at Dosso Dossi’s fashion show last week in Istanbul, where they modelled the Turkish designer’s Spring 2013 collection.
