Paris Hilton kept her baby`s birth a secret from her entire family, the American socialite has revealed. Paris and her husband Carter Reum (41) welcomed a baby boy via surrogacy in January, reports `Mirror.co.uk`. But `The Simple Life` star admitted that she hid her baby`s arrival from her nearest and dearest ones until just before she broke the news to the public on social media.

In an interview with `Harper`s Bazaar` magazine, Paris revealed that she and her partner opted to keep their baby hidden even from their immediate family until she was ready to post the birth announcement on Instagram.
