The blonde beauty made the surprise announcement last Friday (29Apr11).
She has yet to name the father of her child or shed light on whether or not she'll be embarking on motherhood as a single parent.
But her TV colleague Staton, who became a dad himself last year (10), is sure 33-year-old Jones will handle the pressures of having a baby well and easily adapt to her new lifestyle.
He tells People.com, "It's something that she's wanted to do and that she's excited to do. January is such a sweet person... I think she's really going to be a great mother.
"So much of it is natural. It's sort of intimidating, but so much of it comes naturally when you meet the kid."
Jones has been single since she split from former boyfriend Jason Sudeikis in January (11).
