Padma Lakshmi -- the host of "Top Chef" -- kept the identity of her daughter's father a secret, but the secret got out ... and it's some random rich guy you've probably never heard of.
Adam Dell -- brother of the dude who founded Dell computers -- is the mystery man who knocked up the reality show host last year.
According to PEOPLE, Lakshmi and Dell are ironing out visitation rights with their daughter, Krishna, who will be a month old this Saturday.
