Hayden confirmed her engagement to heavyweight boxer Wladimir Klitschko two weeks ago on Live With Kelly and Michael, this weekend at the Environmental Media Awards Saturday she revealed that she designed her 6-carat diamond ring.

‘Montblanc made me this amazing book where they did a bunch of sketches, I told them my idea over time and tweaking things here and there, it came to fruition.’

The Nashville starlet’s emerald cut wedding bling reportedly has a price tag of $500,000.

Since the Ukrainian 37-year-old was otherwise indisposed, Hayden brought along her little brother Jansen. The 19-year-old actor was last seen in this year’s faith-based flick, The Lost Medallion.

Aside from her ring, Panettiere flashed a bit of bra in her sheer lacy frock featuring criss-crossing cut-outs and Halloween colours.

The Golden Globe nominee slicked her blonde locks into a top bun and kept her make-up light and lovely for the environmental event.
