When your mom is a former model and Olympic athlete, you have a good chance of turning out pretty hot. As long as the genes from your dad, who is Donald Trump, stay the hell out of the way. That seems to have happened with Ivanka, who is beautiful by any standard. She's classier than most celebrity offspring (weird, 'cause her dad is Donald Trump and all); she is smart (graduated from Wharton); and she is said to be a good businesswoman.
Classy, smart and business-savvy—good traits but they don't automatically make a girl famous. Nope, the fashion-model looks (and, OK, cartoony mogul dad) did that.
