Kyle Richards and Farrah Answer RHOBH Fans' Questions

Last night's episode of The Real Housewives of Beverly Hills sure left viewers buzzing with questions. Who's Kyle Richards' ex-husband? Which college did daughter Farrah Britt attend? Just how much money did Aunt Kathy Hilton give Farrah for graduation? Luckily the girls spent time in Twitterville to address — mostly — all of these pressing inquiries.

Were you one of the masses wondering about Kyle's ex-husband’s ethnicity? Here's the family tree breakdown: her first hubby, Guraish Aldjufrie, is Indonesian, Arabic, and Dutch. Kyle's current husband, Mauricio Umansky, is Greek and Russian, but born and raised in Mexico. (Side note: he comes from amazing genes -- just look at his mama!) Kyle herself is Irish and Welsh. Mauricio is Jewish and so Kyle converted. And yes, her kids speak Spanish. Whew, you got all that?

Last night's episode focused on Farrah's graduation from college, which proved to be an emotional and proud day for Kyle, who never went to college and had Farrah at 19. @_IamHope tweeted, "@farrahbritt what did u get a degree in?" Answer: Psychology major, business minor from the University of Southern California.

Love the cocktail dress she wore under her cap and gown? The tweets reveal that it's by Jill Stuart, while Kyle's frock came from @PetroZilliaBtq.

But the number of zeroes on that check from the Hilton clan? It remains a mystery.
