Nashville star Hayden Panettiere is engaged to world heavyweight champion Wladimir Klitschko, her on-and-off boyfriend since 2009.

The Golden Globe nominee confirmed the engagement Tuesday on Live with Kelly and Michael. After host Kelly Ripa pointed out the “very large diamond ring” on Panettiere’s left ring finger, she asked, “Does that signify anything? Is that a promise of something?” Panettiere was coy at first, saying, “I think it speaks for itself” — but when Ripa asked point-blank if she was engaged, the actress answered affirmatively.

Panettiere and Klitschko — a Ukranian boxer 13 years her senior and a full one foot, four inches taller than she is — first met at a book party four years ago. The two parted ways in 2011 before reuniting earlier this year.
