"Nashville" star Hayden Panettiere has a lot to sing about ... including her hot bikini body!
The 23-year-old actress showed off her impressive physique while on vacation in Miami on Sunday, stepping into the surf in a purple two-piece.
Hayden is currently in South Beach with boyfriend Wladimir Klitschko, who she may or may not be engaged to.
Reports surfaced last week that the tiny star's large lover popped the question -- but, so far, Panettiere has remained mum on the topic.
The couple may have dropped a clue in an Instagram photo this weekend though, where Hayden was seen wearing a brand new diamond ring. Sure, the sparkler was on her right hand and not the left, but it doesn't help kill the rumors.
