Hayden Panettiere turned heads at ABC's Upfront party Tuesday, and it wasn't just because of her curve-hugging purple dress.
The Nashville star, 23, was seen wearing what some are speculating to be an engagement ring from her boyfriend, Ukrainian boxer Wladimir Klitschko.
Panettiere was spotted wearing the ring in question on her right hand instead of the traditional left hand, but it was quite a sparkler. According to People, the ring features what appear to be several rows of diamonds in a rounded, thick platinum setting. (Coincidentally on Nashville, Panettiere's character, Juliette, was burned last week when she learned her now-ex-boyfriend, Dante (Jay Hernandez), stole money from her to buy a ring for another woman).
Rumors that the Heroes alum was engaged to Klitschko first started in April.
