The CBS News glass slipper fits … Jane Clayson.

Clayson, a correspondent for ABC’s “World News Tonight,” is expected to be named today as the co-host alongside Bryant Gumbel of CBS’ revamped ayem newscast. Internally, Eye web brass dubbed the hunt for Gumbel’s partner “Operation Glass Slipper.”

“The Early Show” is set to bow Nov. 1 from a new street-level studio under construction in the General Motors Building in midtown Gotham. CBS brass have been scouting for a femme co-anchor since May, when plans for an overhaul of the low-rated “This Morning” were confirmed.

Clayson has been with ABC News since 1996. Earlier in her career, she worked in local news in the Salt Lake City market.

CBS News reps would not comment Friday on the hire, but insiders said the deal with Clayson was on track to be finalized over the weekend. There was speculation that ABC News had the right to match CBS’ offer and thereby could derail the deal, but ABC reps could not be reached late Friday.

CNBC’s Maria Bartiromo and ABC’s Elizabeth Vargas were among the other candidates for the co-host slot.

CBS is counting on the reentry of Gumbel to the morning newscast competish to increase its slice of the $400 million ayem advertising market. Gumbel signed a rich deal with CBS in 1997 following a 15-year run on NBC’s “Today.”
