Craig Ferguson announced today that he will step  down as host of CBS' Los Angeles-based ``The Late Late Show'' in December.

``CBS and I are not getting divorced, we are `consciously uncoupling,'  but we will still spend holidays together and share custody of the fake horse  and robot skeleton, both of whom we love very much,'' Ferguson quipped,  referring to the prop characters that appear on his show.

It was not immediately clear if the show will continue with a new host  once Ferguson departs.

``During his 10 years as host, Craig has elevated CBS to new creative  and competitive heights at 12:30,'' according to Nina Tassler, chair of CBS Entertainment. ``He infused the broadcast with tremendous energy, unique  comedy, insightful interviews and some of the most heartfelt monologues seen on  television.''

The Scottish-born Ferguson announced the news during the taping of  tonight's show. The show is taped at CBS Television City in the Fairfax  District.
