Becoming a reality TV star can change a person — and for the cast of Bachelor Nation, that usually means a serious glo up from the days of their cast photo introductions. Though they may have thought they were prepped to step in front of the cameras, it's usually their transformations post-show that are even more dramatic. After all, we know what it takes to look like a Bachelor Nation contestant, and it includes no shortage of eyelash extensions, makeup makeovers, lasering, and even plastic surgery. Last year, more than one Bachelor in Paradise contestant showed up fresh off The Bachelor with a brand new boob job, ready to rock their bathing suits on the beach.
