Olivia Culpo and Danny Amendola either have an open relationship, or someone knows something the other doesn't, cause DA was cupcaking with a chick who looks A LOT like OC.
The Miami Dolphins wide receiver was spotted Saturday laying up next to a mystery chick on a beach in Miami who definitely wasn't Olivia -- even though she's got some serious Olivia look-alike vibes. There are no obvious signs of intimacy -- aside from the hair grazing and lying on each other, of course -- so it's hard to say for sure what's really going on here.
