Hayden Panettiere and long-time boyfriend Wladimir Klitschko have been making headlines lately after a photo of the couple was posted on pal Kate York's Instagram page.

The photo in question appears to show a large ring on the Nashville Star star's wedding finger. While she has yet to address recent engagement rumors, she does admit that it "wouldn't shock" her if the Ukrainian boxer ends up being the father of her children.

"I think it's pretty obvious," Panettiere tells the May issue of Glamour magazine about the couple's rekindled relationship. "I'm not going to deny it."
