Royal Baby Bumps Monday's Siberia

Wills and Kate apparently trump chills and monster-bait.

NBC on Monday pre-empted the regularly scheduled episode of Siberia for A Little Prince, a Dateline special about the newest member of England’s royal family.

The hour-long special, hosted by NBC News’ Natalie Morales, promises to “provide viewers with an intimate look inside the lives of the Duke and Duchess of Cambridge” who Monday became first-time parents to an as-yet-unnamed son.

A Little Prince will air at 10/9c.  Siberia‘s “Fire in the Sky” episode, originally scheduled for this evening, will air next Monday.

Meanwhile, ABC will broadcast The Royal Baby: Heir to the Throne, a Barbara Walters-anchored special edition of 20/20, Tuesday at 10 pm in place of a Body of Proof repeat.
