Hayden Panettiere showed off her incredibly toned bikini body on Sunday in Miami Beach, following rumors that she's secretly engaged to heavyweight boxer Wladimir Klitschko.
Neither the 23-year-old actress, nor her rumored fiance, 37, have publicly commented on rumors of their engagement; however, Panettiere has been spotted wearing that diamond ring in several photos she's posted to her social media accounts in the days following the rumors.
The couple began dating in 2009, before splitting in 2011, blaming the breakup on long distance. "We have an amazing amount of love and respect for each other and remain very close friends," she said in a statement at the time. In January 2013, they rekindled the romance, and sources say they are looking to keep things quiet before they tie the knot in a summer wedding, according to Us Weekly's sources.
