Hayden Panettiere engagement rumors have gone viral after the Nashville star was photographed wearing a huge diamond ring on her left hand as she walked through an airport. Wladimir Klitschko, however, was not on hand to greet his girlfriend.

Panettiere and Klitschko, a heavyweight boxer, have been the subject of engagement speculation for months, and now it appears that the actress is finally ready to say "I do." This May, the 23-year-old was asked if she was engaged to be married to Klitschko, and Panettiere gave a telling reply. “No ring,” she said, while holding up her left hand. Now, however, there is a ring on her finger and the enormous square diamond is certainly proposal-worthy.

It’s not the first time Panettiere has donned a diamond ring. In April, the 5-foot-2 actress was photographed wearing a sparkler while her buff boyfriend carried her in an embrace. Yet, upon further inspection, the rumored engagement ring was determined to be on Panettiere’s right hand. And while the media remains obsessed with the prospect of Panettiere marrying Klitschko, the blonde beauty merely laughs off the constant attention.

“It blows my mind sometimes that us getting together has gotten so much attention. It’s like, really? This is breaking news?,” Klitschko’s rumored fiancée said. “An acquaintance of ours did a coffee-table book….We met at the party for the launch of the book,” Panettiere explained. “We’ve been friends for five years, we’ve never not been close,” the actress added.

Aside from her love life and potential marriage plans, Panettiere is busy with her hit television show, Nashville, based on the country music business. “The music was a draw for me. I love singing and I love country music. I was a little nervous about some of the songs, as it’s a very specific genre of country music, but over time I really got into it,” she said of her role as Juliet. Indeed, Panettiere's love of country runs so deep that she ditched Hollywood for Tennessee.

“Home is now Nashville. I moved there to immerse myself in it all. But now, even if something did happen to the show, Nashville will always be a part of my life and I’ll always have a base there,” the newly engaged star said.
