Hayden Panettiere had three things to flaunt during the ABC Upfront event on Tuesday, May 14: her super-toned bod, gorgeous diamond ring and her sexy fiance, Wladimir Klitschko.

Wearing a cleavage-baring purple studded bandage-style dress, the Nashville actress, 23, completed her sexy and sultry look with smoky eye makeup and a side French braid.

Her Ukranian boxer beau, 37, seemed to approve -- as the two shared some sweet PDA moments on the red carpet. Panettiere was all smiles flashing her diamond-encrusted ring, which she wore on her right hand.

Us Weekly exclusively reported back in April that Panettiere and Klitschko got engaged after reconciling in January. The two previously had dated for two years before taking a 19 month break in May 2011.
